    Overbite in Children: A Real 6-Month Preortho Growth Treatment Case

    SummaryWhat causes protruding front teeth and overbite in children, and when should orthodontic treatment start? This article covers a real case of an elementary school student whose growth orthodontics changed in 6 months with Preortho, along with the right age for a first checkup, daily wear time, and what to watch for after treatment. Helpful for parents of growing children.

    Upper front teeth that stand out whenever a child smiles
    are often dismissed as “just genetics,” but that’s not always the whole story.

    Protruding front teeth in children have been linked to up to a 3-fold higher risk of front tooth injury compared with children who don’t have this trait, according to research.

    In this article, we’ll look at a case where protruding front teeth and overbite occurred together, and walk through how 6 months of growth orthodontics with Preortho played out.

    Key Points
    Key Summary
    Protruding front teeth in children are often a form of Class II malocclusion caused by slower lower jaw growth, and may appear alongside an overbite.
    Both the Korean Association of Orthodontists and the American Association of Orthodontists (AAO) recommend a first orthodontic checkup around age 6–7, and related research reports a lower rate of new front tooth injury in early-treatment groups compared with delayed-treatment groups (19% vs. 30%).
    This article covers a case in which overjet and overbite were observed to improve over 6 months using a Preortho Type1 appliance.

    Why Do Children Get Protruding Front Teeth?

    Protruding front teeth in children are reported to result more often from slower lower jaw growth than from an oversized upper jaw.

    In orthodontics, this condition is called Class II malocclusion.
    The front-to-back gap between the upper and lower front teeth is called overjet.
    A normal range is generally when the upper front teeth sit about 2–3mm ahead of the lower front teeth.

    As this gap increases, the front teeth appear to stick out more.

    Jaw shape is strongly influenced by genetics, and oral habits such as thumb sucking, lip sucking, and mouth breathing can also negatively affect tooth alignment.

    There’s one more thing to note.
    A systematic review found that when overjet exceeds 3–3.5mm, the risk of front tooth injury roughly doubles, and beyond 6mm it can rise to about 3 times higher.
    (Kids really do fall a lot…)


    Is It Okay to Leave an Overbite in Children Untreated?

    If left untreated, a severe overbite can lead to gum damage or excessive tooth wear, so a proper diagnosis is needed.

    An overbite (deep bite) refers to a condition where the upper front teeth overlap the lower front teeth so much that, when biting down on the back teeth, the lower front teeth are barely visible.
    It’s a common type of malocclusion that often appears together with protruding front teeth and a recessed chin.

    Protruding front teeth in children - image 3

    In severe cases, the lower front teeth can dig into the palate gum tissue or cause excessive tooth wear.

    Caution
    Many parents worry about a link to TMJ (jaw joint) disorders. While some reports note an association, there isn’t yet enough evidence to conclude that an overbite directly causes TMJ disorders. If there is jaw joint pain or clicking, we recommend a separate consultation with a specialist.

    When and How Should Growth Orthodontics Start?

    The honest answer is “it depends on the child,” which is exactly why getting an orthodontic checkup around age 7 matters.

    Starting treatment as early as possible isn’t automatically right, and neither is simply waiting.
    That’s why the timing of permanent front teeth eruption is used as a reference point.

    “See an orthodontist for a checkup at age 7”

    The Korean Association of Orthodontists is reportedly running a public awareness campaign with this message, recommending a first orthodontic checkup around age 7. The American Association of Orthodontists (AAO) similarly recommends a first checkup no later than age 7.

    An international systematic review (a Cochrane-affiliated study) found that the rate of new front tooth injury was 19% in the group that received first-phase treatment at ages 7–11, compared with 30% in the group treated only once during adolescence.
    However, there was no clear difference in final outcomes between the two groups once all treatment was complete.

    That’s why the principle is to diagnose first, and choose the appliance afterward.

    Item Details
    First orthodontic checkup Around age 7
    Checking for a recessed-chin tendency Typically during the late-elementary growth spurt, or earlier in severe cases
    Age range for Preortho use From about age 5–6 up to around age 12
    Preortho treatment duration Typically 6 months to 1 year
    Daily wear time Manufacturer recommendation: 1+ hour during the day plus 8+ hours at night (our clinic recommends 12+ hours)
    After all permanent teeth erupt Second-phase orthodontics if needed
    Checklist
    ✅ Has your child had an orthodontic checkup around age 7?
    ✅ Does your child have oral habits like thumb sucking or lip sucking?
    ✅ Do the front teeth look more protruded as the permanent ones come in?
    ✅ Do the upper teeth appear to cover the lower teeth significantly?

    What Actually Changed After Wearing Preortho?

    This is the case of an elementary school patient who came in concerned about protruding front teeth and difficulty closing the lips fully.

    Protruding front teeth in children - image 4

    Protruding front teeth in children - image 5

    The intraoral photos showed the upper front teeth positioned excessively ahead of the lower front teeth, with an overbite in which the upper teeth covered almost all of the lower teeth.
    The occlusal view also suggested limited space for the permanent teeth to erupt.

    Since the first molars and lateral incisors had not yet erupted, it was a bit early for a removable appliance or clear aligners (Invisalign First).
    So the appliance chosen was Preortho, a silicone mouthguard-type appliance.

    Preortho is broadly divided into Type1 and Type3.
    Type3 is used for underbite/crossbite cases, while Type1 is used for protruding front teeth and overbite.

    Protruding front teeth in children - image 6

    What Does Preortho Type1 Aim to Achieve?

    Type1 targets five goals.

    1. Reducing protruding front teeth
    2. Improving overbite
    3. Encouraging lower jaw growth
    4. Mild arch expansion
    5. Mild front teeth alignment

    For this patient, all five goals aligned with what was needed, so treatment began right away.

    By around the 3-month mark, the upper front teeth appeared to move inward, with overjet appearing to decrease and the overbite appearing to improve as well.

    Protruding front teeth in children - image 7

    Preortho wear was then completed at the 6-month mark.

    Protruding front teeth in children - image 9

    Protruding front teeth in children - image 10

    Result
    The lower front teeth, previously more than half hidden by the overbite, appeared to become more visible.
    The upper front teeth, which had been excessively advanced relative to the lower front teeth, were also observed to have moved inward.

    Protruding front teeth in children - image 11

    Protruding front teeth in children - image 12

    The occlusal view appeared to show that both the upper and lower arches had widened, and the previously spaced-out upper front teeth appeared more aligned.

    Growth-phase treatment is less about finishing orthodontics and more about guiding the direction of growth.
    Even in cases where extraction would be unavoidable for an adult, guiding growth in the right direction can sometimes achieve adequate results without extraction.
    However, once all permanent teeth have erupted, second-phase orthodontics for tooth alignment may still be needed.

    Cheongnyangni Yonsei Dajeonghan Orthodontic Clinic, located in Cheongnyangni, Dongdaemun-gu, Seoul, is an orthodontic specialty clinic where the director — board-certified in both orthodontics and integrated dentistry — personally handles everything from the initial consultation to appliance removal.


    Frequently Asked Questions

    1. At what age should a child with protruding front teeth get checked?
    We recommend an orthodontic checkup around age 7. A checkup doesn’t mean treatment starts immediately — the right timing varies by child.

    2. How many hours a day should Preortho be worn?
    The manufacturer recommends at least 1 hour during the day and 8+ hours while sleeping. Our clinic recommends at least 12 hours of wear per day.

    3. If a child does growth orthodontics, will they need braces later?
    Second-phase orthodontics for tooth alignment may still be needed once all permanent teeth have erupted.

    4. What happens if an overbite is left untreated in children?
    In severe cases, it can cause the lower front teeth to dig into the gums or lead to excessive tooth wear, so a proper diagnosis is important.

  • Non-Surgical Underbite Correction: 3 Criteria You Need to Know

    Non-Surgical Underbite Correction: 3 Criteria You Need to Know

    SummaryA protruding lower jaw doesn’t automatically mean you need surgery. This guide covers the skeletal criteria for non-surgical underbite correction, how to tell a pseudo (dental) underbite apart, typical treatment timelines, and what to check when reading non-surgical underbite correction reviews.

    When you notice your lower jaw standing out in profile, it’s easy to assume jaw surgery is the only option.
    However, if the difference in jaw bone size is minor and the main issue is how the teeth are arranged, non-surgical underbite correction alone may be able to correct the bite.

    Even so, many people look into surgery first without knowing these criteria.
    With a thorough consultation and diagnosis, some cases are reported to improve with orthodontic treatment alone, without surgery.

    Key Takeaways
    If your back teeth bite normally but only your front teeth meet in reverse — a pattern known as a pseudo (dental) underbite — non-surgical underbite correction may help improve the bite.
    Treatment typically takes about 18 to 30 months, and the first step is always an accurate 3D CT scan to measure any skeletal discrepancy.
    Below, we outline the specific criteria for non-surgical correction and what to watch for when reading treatment reviews.

    What Causes an Underbite, and What Types Are There?

    non-surgical underbite correction

    To put it simply, underbites fall into two categories — skeletal and dental — and the more dental the cause, the better the odds for non-surgical correction.
    An underbite refers to a condition in which the lower jaw protrudes forward relative to the upper jaw or grows excessively.

    Asan Medical Center classifies an underbite as a type of malocclusion.
    Below is the definition published by the hospital.

    An underbite (mandibular protrusion, mandibular prognathism) occurs when the lower jaw is abnormally large relative to the upper jaw, resulting in malocclusion.

    According to Asan Medical Center’s health information, this is how it’s explained.
    An underbite is classified as Class III malocclusion.

    Causes include not only genetic jaw growth patterns but also habits such as tongue-thrusting or mouth breathing.
    Viewed from the front, it’s often accompanied by facial asymmetry, and from the side, the lower third of the face tends to look elongated.

    non-surgical underbite correction illustration 7

    Key Point
    Not every underbite requires surgery.
    If the difference in jaw bone size is minor and tooth position is the main issue, bite adjustment alone may bring improvement.
    A detailed diagnostic exam is the first step toward understanding exactly where you stand.

    What Are the Criteria for Non-Surgical Underbite Correction?

    non-surgical underbite correction illustration 8

    In short, this approach is an option when the size difference between the upper and lower jaw bones is minor and the back teeth already bite normally.
    Non-surgical underbite correction is a treatment that aims to improve a reverse bite through tooth movement and bite adjustment alone, without jaw surgery.

    This approach is reported to be particularly effective for a pseudo (dental) underbite, where the back teeth bite correctly but only the front teeth meet in reverse.
    In these cases, moving the teeth backward or adjusting their angle can help create a normal bite.

    Category Non-Surgical Correction Possible Surgery Required
    Jaw bone size difference Minor Clearly significant
    Molar (back teeth) bite Normal bite Misaligned
    Main cause Tooth position/angle (pseudo underbite) Excessive skeletal growth itself
    Treatment method Adjustment with orthodontic appliances alone Orthodontics combined with jaw surgery

    non-surgical underbite correction illustration 9

    Changes You May Expect
    ✅ Moving the lower dental arch backward can help the upper and lower teeth meet more normally.
    ✅ Correcting the angle of front teeth that previously met in reverse may help improve the reverse bite.
    ✅ Chewing may feel more comfortable, and the lip line may look more natural as a result.

    Treatment length varies from person to person, but non-surgical correction generally takes about 18 to 30 months.
    Cases like a pseudo underbite, where only tooth alignment needs adjusting, can sometimes finish sooner.

    Timing also matters for growing children — the Korean Association of Orthodontists recommends starting treatment around ages 7 to 9 if a skeletal reverse bite is suspected.
    This recommendation applies specifically to children who are still growing; whether non-surgical correction is possible for an adult needs to be determined through a separate diagnosis.


    Reading Non-Surgical Underbite Correction Reviews: What to Look For

    non-surgical underbite correction illustration 10

    A review is only meaningful if you look past subjective impressions and focus on bite measurements and the treatment process.
    A trustworthy review is one that includes before-and-after bite data from a case with a jaw structure similar to your own.

    You need to objectively assess how much improvement in appearance and function is realistic through tooth movement alone, within the limits of the jaw bone itself.
    Rather than taking someone else’s success story at face value, check first whether the treatment plan actually fits your own oral structure.

    non-surgical underbite correction illustration 11

    Checklist
    ✅ Was the degree of skeletal discrepancy accurately measured with a 3D CT scan?
    ✅ Was it confirmed that the upper and lower teeth bite evenly after treatment?
    ✅ Was the treatment plan based on a range of clinical cases?

    Because outcomes for underbite correction vary depending on each person’s individual jaw structure, a detailed diagnostic exam is essential.


    How Do You Care for Your Orthodontic Appliance Safely?

    non-surgical underbite correction illustration 12

    The key to safe management is keeping up with regular visits and thorough at-home care.
    How finely the force from the appliance is adjusted directly affects how the teeth move and how the bite ultimately turns out.

    Food tends to get trapped around the appliance easily, so it’s important to make active use of oral hygiene tools.

    non-surgical underbite correction illustration 13

    Precautions
    Chewy or hard foods can dislodge the appliance or put excess strain on tooth movement, so it’s best to avoid them.
    Skipping regular checkups can cause the bite to end up not aligning as planned.

    Following your provider’s guidance for thorough home care alongside regular checkups can help support a well-balanced result.
    If you’re wondering whether your own case meets the criteria for non-surgical correction, consult an orthodontic specialist first.

    Frequently Asked Questions

    non-surgical underbite correction illustration 14

    1. Can every underbite be corrected with orthodontics alone, without surgery?
    If the skeletal discrepancy is very severe, orthodontic treatment combined with surgery may be necessary, so a detailed diagnosis should always come first.

    non-surgical underbite correction illustration 15

    2. How long does non-surgical underbite correction usually take?
    It varies depending on the speed of tooth movement and the severity of the malocclusion, but it generally takes about 18 to 30 months.
    Cases involving only tooth alignment, like a pseudo underbite, may finish sooner.

    non-surgical underbite correction illustration 16

    3. What should I watch out for most when reading reviews?
    Rather than relying on someone else’s subjective impressions, it’s important to check whether the case involves a jaw structure similar to your own.

    non-surgical underbite correction illustration 17

    4. Why is it essential to wear a retainer after orthodontic treatment?
    Teeth naturally tend to shift back toward their original position, so a retainer is essential for keeping the bite stable over the long term.

  • Facial Asymmetry Orthodontic Treatment: 4 Key Diagnostic Steps

    Facial Asymmetry Orthodontic Treatment: 4 Key Diagnostic Steps

    SummaryThis article looks at how facial asymmetry orthodontic treatment works at Dongdaemun Orthodontics. From bite diagnosis and 3D CT imaging to jaw joint and muscle evaluation and tips for maintaining facial balance, here’s everything worth knowing before your visit.

    Have you ever noticed that one side of your face looks noticeably larger every time you check the mirror?

    In fact, this appearance is far more often caused by a misaligned bite between the upper and lower teeth than by a truly severe skeletal asymmetry.

    That’s exactly why Dongdaemun Orthodontics pays such close attention to the left-right balance of the chewing muscles as part of every evaluation.

    Key Takeaways
    Dongdaemun Orthodontics evaluates both tooth alignment and how the upper and lower jaws come together, which may help the appearance associated with facial asymmetry improve naturally over the course of facial asymmetry orthodontic treatment.
    The process relies on 3D CT imaging and facial analysis equipment to map the relationship between the skeleton and the teeth, then plans tooth movement around the center line of the face.
    A significant share of Korean adults live with some degree of malocclusion, which is why identifying the underlying cause through precise diagnosis is such an important first step.

    Dongdaemun Orthodontics

    If crooked teeth have you considering orthodontic treatment,
    it helps to look beyond simply straightening the teeth
    and also consider how the teeth show when smiling and the overall shape of the mouth.

    Because the cause of crooked teeth differs from person to person,
    what needs to be checked also depends on whether the issue is limited to tooth alignment or also involves the position of the upper and lower jaws.

    Dongdaemun Orthodontics related image 2

    Can Orthodontic Treatment Alone Improve Facial Asymmetry?

    Dongdaemun Orthodontics related image 3

    When the skeleton itself isn’t severely asymmetrical,
    orthodontic treatment alone may help improve the appearance of facial asymmetry.

    Facial asymmetry refers to a condition where, relative to the center line of the face, the eyes, cheekbones, or corners of the mouth appear uneven in height or size from left to right.

    There are broadly two causes:
    skeletal asymmetry, where the bone itself grew unevenly,
    and functional asymmetry, where a misaligned bite causes the chewing muscles to develop unevenly on one side.

    Dongdaemun Orthodontics related image 4

    Seoul National University Hospital describes malocclusion as follows.

    Malocclusion refers to a condition in which the upper and lower jaws do not come together normally, or the teeth are uneven and crooked.

    Dongdaemun Orthodontics related image 5

    Type Main Cause Effect of Orthodontic Treatment
    Functional asymmetry Misaligned bite position, one-sided chewing habits May improve with orthodontic treatment alone
    Skeletal asymmetry Uneven growth of the jawbone itself Treatment direction must be determined after precise diagnosis

    According to a report by Edaily, surveys indicate that more than one in two Korean adults experiences some degree of malocclusion,
    so this is a common concern rather than a rare one.

    Key Point
    Simply straightening the teeth into a line doesn’t address an underlying skeletal imbalance, and an unnatural look can remain.
    Analyzing the face’s center line together with the horizontal bite relationship is what allows both function and appearance to be addressed at the same time.

    Dongdaemun Orthodontics related image 6


    How Does Dongdaemun Orthodontics Perform a Precision Diagnosis?

    Dongdaemun Orthodontics related image 7

    A precise diagnosis at Dongdaemun Orthodontics begins with combining 3D CT imaging and facial analysis equipment.

    Rather than simply photographing the inside of the mouth,
    examining the three-dimensional structure of the skull and jawbone is what makes an accurate treatment plan possible.

    It’s especially important that the plan also factors in details such as how much gum shows when smiling and lip thickness.

    1. Simulating in advance the direction the teeth will move and how the bone is likely to develop
    2. Thoroughly evaluating the condition of the jaw joints and the tension in the surrounding muscles
    3. Setting the bite position in line with the overall balance of the face

    Dongdaemun Orthodontics related image 8

    Key Point
    3D CT analysis examines the jawbone and surrounding muscles in three dimensions, not just the teeth, which can help reduce variables during treatment and improve predictability.

    In recent years, the number of orthodontic patients aged 40 and older has been steadily rising.

    According to a Korean Association of Orthodontists survey reported by Dental Times (Daily Dental) in 2018, the share of orthodontic patients aged 40 and older grew from 4.9% in 2010 to 6.1% in 2017,
    while the proportion of new patients in their 40s starting treatment climbed from just 1.2% in 2000 to 9.3% in 2017.

    This is exactly why precise diagnosis to pinpoint the exact cause matters even more for adults whose growth is already complete.


    How Can You Maintain Facial Balance During Orthodontic Treatment?

    Dongdaemun Orthodontics related image 9

    Treatment at Dongdaemun Orthodontics tracks not just how quickly the teeth move,
    but also changes in the surrounding soft tissue, such as the lips and cheeks.

    As the teeth shift and the profile of the mouth changes, fine adjustments are made so the angle between the nose and chin stays in harmony,
    and progressing gradually in stages — rather than forcing rapid change — tends to produce a more natural-looking result.

    Checklist
    ✅ From the front, check whether the center line of the face lines up with the center line of the teeth
    ✅ From the side, check whether the nose, lips, and chin form a balanced profile
    ✅ Check whether chewing force is distributed evenly rather than concentrated on one side

    Dongdaemun Orthodontics related image 10

    Adjusting the appliance to the individual based on thorough bone analysis may help support left-right symmetry over the course of treatment.

    The goal isn’t simply straightening the teeth —
    it’s completing the balance of the whole face alongside that.


    What Kind of Care Is Needed During Treatment?

    Dongdaemun Orthodontics related image 11

    Once the appliance is attached, it’s important to keep strictly to a schedule of regular dental visits.

    That’s because the fine adjustments made to the force applied to the teeth have a major effect on overall bone alignment and facial balance.

    Food also tends to get caught around the appliance easily,
    so it’s important to actively use oral hygiene tools such as interdental brushes and floss to keep the area clean at all times.

    Caution
    Chewy or hard foods can dislodge orthodontic appliances or place unnecessary strain on tooth movement, so it’s best to get in the habit of avoiding them where possible.

    Dongdaemun Orthodontics related image 12

    What You Can Expect
    With thorough at-home care and regular checkups following your provider’s guidance, not just the alignment of the teeth but a more balanced overall appearance can gradually take shape.

    If you’re researching orthodontic clinics in the Dongdaemun area,
    checking treatment information first on the Cheongnyangni Yonsei Dajeonghan Orthodontics website is one way to get started.

    Frequently Asked Questions

    1. Can orthodontic treatment alone improve facial asymmetry?
    If the asymmetry isn’t caused by a severe skeletal issue but rather by a misaligned bite that makes the face look uneven, orthodontic treatment may help bring about improvement.

    2. How is a precision diagnosis carried out?
    It combines 3D CT imaging, an intraoral scan, and detailed facial measurements to analyze the relationship between the skeleton and the teeth in three dimensions.

    Dongdaemun Orthodontics related image 14

    3. Does attaching an appliance also change the shape of the face?
    As the protrusion of the mouth area decreases or the jawline becomes more defined, changes in overall appearance can occur. That said, the degree of change varies from person to person.

    4. Is there anything to be especially careful about during treatment?
    To avoid damaging the appliance, steer clear of sticky or hard foods, and brush thoroughly to help prevent cavities.

    Dongdaemun Orthodontics related image 15

    5. Can adults get facial asymmetry orthodontic treatment at Dongdaemun Orthodontics too?
    Yes — adults whose growth has finished can proceed with treatment once the cause is identified through precise diagnosis, and the proportion of patients aged 40 and older has in fact been rising steadily.

  • Early Orthodontic Treatment Timing: 3 Reasons to See a Board-Certified Orthodontist

    Early Orthodontic Treatment Timing: 3 Reasons to See a Board-Certified Orthodontist

    SummaryMissing the ideal early orthodontic treatment timing can mean losing the golden window for correcting jaw growth without surgery. Here’s what to know about growth-stage development and why care should come from a board-certified orthodontist.

    Has your child mentioned jaw discomfort while eating, yet you keep putting off that dental appointment?

    Meanwhile, your child’s jawbone is growing right now, in this very moment.
    During the growth years, there’s a golden window when skeletal issues can often be corrected without surgery.

    To avoid missing this window,
    you first need to understand the criteria for judging the right early orthodontic treatment timing.

    This article outlines the growth-stage checkpoints for catching the right early orthodontic treatment timing, along with the medical reasons treatment should be provided by a board-certified orthodontist.
    We’ll walk through everything from the principles of jaw growth to the guidelines for safely caring for orthodontic appliances.

    When Is the Right Time for Early Orthodontic Treatment?

    To answer directly: the ideal time for a first checkup is around age 6 to 7, when permanent teeth begin coming in.

    Growth-stage oral development refers to the process in which baby teeth fall out and permanent teeth emerge, while the upper and lower jawbones grow together.

    If skeletal imbalances go unaddressed during this stage, they can lead to facial asymmetry or severe malocclusion.

    That’s why careful, early observation to catch warning signs is so important.

    early orthodontic treatment timing illustration 3

    early orthodontic treatment timing illustration 4

    early orthodontic treatment timing illustration 5

    Key Point
    Because a child’s jaw growth can sometimes be guided to correct skeletal imbalances without surgery, it’s important not to miss the right early orthodontic treatment timing — the golden window.
    Genetic factors and habits like thumb-sucking or mouth breathing are also major contributors that can interfere with normal growth.

    early orthodontic treatment timing illustration 6

    early orthodontic treatment timing illustration 7

    early orthodontic treatment timing illustration 8


    How Does Early Orthodontic Treatment Manage Jaw and Teeth Growth?

    Early orthodontic treatment is less about moving teeth with appliances and more like orthopedic treatment that guides the direction of jaw growth.

    Early (pediatric) orthodontic treatment refers to guiding or restraining jaw growth during the growth years to balance the upper and lower jaws while also correcting related muscle function.

    Here’s what this approach can help achieve:

    1. Creating space for permanent teeth to erupt correctly
    2. Guiding harmonious growth of the upper and lower jawbones
    3. Helping prevent malocclusion by correcting oral habits

    early orthodontic treatment timing illustration 9

    Category Growth-Stage (Pediatric) Orthodontics Adult Orthodontics
    Treatment Goal Guiding/restraining jaw growth Focused on aligning teeth
    Main Methods Orthopedic appliances, growth-guidance appliances Brackets, clear aligners, etc.
    Possible Benefit May reduce the likelihood of extraction or surgery Proceeds based on an already-formed skeletal structure

    Because every child’s growth rate and skeletal pattern differs,
    a one-size-fits-all approach should be avoided.

    Building an individualized treatment plan based on an accurate diagnosis is what matters most.

    early orthodontic treatment timing illustration 10

    early orthodontic treatment timing illustration 11


    Why Should Early Orthodontic Treatment Be Done by a Board-Certified Orthodontist?

    A board-certified orthodontist is a dentist who completed one year of internship and three years of residency training exclusively in orthodontics at an institution recognized by Korea’s Ministry of Health and Welfare, and who has passed the national specialist licensing exam.

    Growth-stage orthodontic care is a complex discipline that must consider not only a child’s current tooth alignment but also how the facial bones will develop into adulthood.

    That’s why it demands the ability to anticipate skeletal growth patterns and judge long-term prognosis.

    Checklist: What to Consider When Choosing a Provider
    ✅ Confirm the provider holds a Ministry of Health and Welfare–certified orthodontic specialist qualification
    ✅ Look for experience across a range of growth-stage cases and a precise diagnostic system
    ✅ Confirm they offer systematic, long-term prognosis management

    You can also verify specialist credentials on the Korean Association of Orthodontists (KAO) website.

    This expertise may help reduce variables that can arise during treatment and support overall safety.
    If you’re considering early orthodontic treatment in the Cheongnyangni area, visit the Cheongnyangni Yonsei Dajeonghan Orthodontics homepage to check whether care is provided by a board-certified orthodontist.

    How Do You Safely Care for Pediatric Orthodontic Appliances?

    During early orthodontic treatment, appliance hygiene and regular follow-up visits matter most.

    Neglecting to brush after meals can make cavities and gum disease more likely, so attentive guidance from parents or guardians is essential.

    Caution
    If an appliance becomes bent or damaged, do not try to adjust it yourself — see your dental provider right away for an inspection.

    early orthodontic treatment timing illustration 16

    Ongoing Care
    Regular checkups to track tooth movement and jaw growth, combined with following your orthodontist’s guidance on appliance wear, can support consistent care and systematic progress monitoring.

    Frequently Asked Questions

    1. When should my child have their first orthodontic checkup?
    It’s recommended to have a first checkup around age 6 to 7, when permanent teeth begin coming in, to assess skeletal development.

    2. If my child gets early orthodontic treatment, will they avoid needing treatment again as an adult?
    Correcting skeletal imbalances early, during the growth years, may help reduce the difficulty of future adult orthodontic treatment and the likelihood of extraction — though it does not guarantee that no further treatment will be needed.

    3. How is a board-certified orthodontist’s care different from general dental care?
    Board-certified orthodontists draw on specialized knowledge of jawbone tendencies and overall facial skeletal harmony, not just tooth alignment, to build a precise treatment plan.

    4. Will wearing an appliance get in the way of daily life?
    There may be some initial discomfort or a sense of foreign material in the mouth, but children often adjust within a few days and return to their normal routine.

  • Kids Orthodontic Appliance Cleaner: 3 Tips to Protect PreOrtho Effectiveness

    Kids Orthodontic Appliance Cleaner: 3 Tips to Protect PreOrtho Effectiveness

    SummaryChoosing the right kids orthodontic appliance cleaner is key to preserving PreOrtho effectiveness. This guide covers hygienic ways to care for kids’ silicone orthodontic appliances without toothpaste, precautions for use during the growth phase, and a handy checklist — routines even first-time parents can follow right away.

    Have you ever noticed a silicone orthodontic appliance turn cloudy after cleaning it with toothpaste?
    That’s because the abrasive particles in toothpaste leave tiny, invisible scratches on the surface — and bacteria multiply easily in those grooves.

    The PreOrtho effect, used to support oral myofunctional development in growing children, depends as much on proper cleaning habits as on the appliance itself.
    Let’s go over how to choose the right cleaner and care for the appliance correctly.

    PreOrtho effect

    This article covers the PreOrtho effect and how it works, how to choose the right cleaner for a silicone appliance, and what to watch for when a growing child wears it.
    Choosing the right cleaner can make a big difference in the appliance’s lifespan and hygiene, so we recommend reading through to the end.

    PreOrtho effect illustration 2

    What Kind of Kids’ Orthodontic Appliance Is PreOrtho?

    PreOrtho effect illustration 3

    PreOrtho isn’t a device that forces teeth into position — it’s a functional appliance designed to help balance the muscles inside the mouth.

    PreOrtho is a removable silicone appliance that supports oral myofunctional development in growing children and can help teeth find their proper position.
    Because it’s made of soft silicone, it causes little discomfort, and children can insert and remove it themselves as part of their daily routine.

    By helping correct poor tongue and lip muscle habits, it can contribute to creating the space the jawbone and teeth need to grow naturally.

    PreOrtho effect illustration 4

    Key Point
    Rather than pushing teeth directly, PreOrtho is a functional appliance that helps a child’s facial bones grow naturally by balancing the muscles inside the mouth.

    PreOrtho effect illustration 5

    This approach makes use of a growing child’s natural jaw growth to help the facial bones and teeth develop in harmony.
    It may also help lower the likelihood of needing more complex orthodontic treatment later on.

    That’s why it’s important not to miss the window when a child’s bones are growing most actively, and to start at the right time.

    PreOrtho effect illustration 6

    PreOrtho effect illustration 7


    What PreOrtho Effects Can You Actually Expect?

    PreOrtho effect illustration 8

    The PreOrtho effect varies depending on how consistently a child wears the appliance and how well poor oral habits are corrected.

    It helps guide the tongue into its proper resting position and encourages nasal breathing instead of mouth breathing, which can help relax tension in the jaw joint and surrounding muscles.
    Through this, the following changes can be expected.

    PreOrtho effect illustration 9

    • Correction of poor oral habits and improved muscle function
    • Creating space for teeth to erupt properly
    • Guiding teeth toward a more even alignment
    • Easing skeletal imbalance during the growth period

    PreOrtho effect illustration 10

    Expected Results
    Building a foundation for a healthy oral environment through consistent wear is an important part of the process.
    That said, results can vary somewhat depending on a child’s growth rate and dental condition.

    PreOrtho effect illustration 11


    How Should You Choose a Kids Orthodontic Appliance Cleaner?

    PreOrtho effect illustration 12

    Choosing the right cleaner is essential for keeping the appliance hygienic and usable for longer.
    A dedicated appliance cleaner is a product that cleans the silicone surface thoroughly without any abrasive ingredients.

    Because of the nature of silicone, cleaning it with regular toothpaste can leave invisible micro-scratches caused by the abrasive particles in the toothpaste.
    Bacteria can multiply easily within those scratches, so it’s safer to always use a cleaner made specifically for the appliance.

    Category Regular Toothpaste Dedicated Appliance Cleaner
    Abrasive ingredients Yes No
    Risk of surface scratches High Low
    Risk of bacterial growth Present Minimal

    PreOrtho effect illustration 13

    Checklist
    ✅ Use a dedicated appliance cleaner instead of regular toothpaste
    ✅ Rinse with lukewarm or cold water instead of hot water
    ✅ Rinse thoroughly after cleaning so no residue remains
    ✅ Regularly check the appliance surface for warping or tears

    PreOrtho effect illustration 14

    Caution
    Silicone is sensitive to heat, so it can warp easily if left in hot water or inside a car during summer.
    After cleaning, always store the appliance in its dedicated case.

    What Should You Watch Out for When a Growing Child Uses the Appliance?

    PreOrtho effect illustration 15

    To support the PreOrtho effect, it’s essential to keep the appliance from warping and to follow the recommended wear time.

    Because silicone is sensitive to heat, it can warp if left somewhere hot, so it’s important to build the habit of always storing it in its dedicated case.
    Good results are more likely when attentive parenting is combined with the child’s cooperation.

    It’s a good idea to visit the dentist regularly to have both the appliance and the child’s dental growth checked together.
    If you’d like a more detailed consultation, please visit the Yonsei Dajeonghan Orthodontics Cheongnyangni website.

    Tips for Safe Care
    When heading out, always keep the appliance in its dedicated case so it doesn’t get lost.
    Thorough hygiene care combined with proper wear habits together help build a healthy oral environment for your child.

    PreOrtho effect illustration 16


    Frequently Asked Questions

    PreOrtho effect illustration 17

    1. How many hours a day should the appliance be worn?
    Typically, wear time combines nighttime sleep hours with periods after school, adding up to the recommended daily total.

    2. Can I use regular soap instead of a cleaner?
    Soaps with strong cleaning agents can leave residue in the mouth, so it’s best to use a kids orthodontic appliance cleaner made specifically for the appliance whenever possible.

    3. When does the PreOrtho effect start to show?
    This varies with a child’s growth rate and wear habits, but changes generally appear gradually after several months or more of consistent use.

    4. What should I do if the appliance breaks?
    Don’t try to adjust it yourself — be sure to visit the dental clinic for a checkup.

    5. Where can I buy a dedicated cleaner?
    Most are available through your dentist’s recommendation or at oral care product retailers.

  • Mesiodens Treatment: 3-Step Orthodontic Space Closure After Extraction

    Mesiodens Treatment: 3-Step Orthodontic Space Closure After Extraction

    SummaryLeaving a mesiodens untreated can block permanent tooth eruption and damage the roots of neighboring teeth. Here’s a look at a mesiodens treatment case involving extraction and orthodontic space closure at a Cheongnyangni dental clinic.

    If you’ve noticed one extra small tooth growing between your upper front teeth, have you been brushing it off as no big deal?
    Left alone, it can gradually cause the roots of a neighboring tooth to resorb.

    This unfamiliar tooth is often a mesiodens.
    When it’s found and how it’s treated can significantly change the shape of the entire dental arch.

    This article covers why a mesiodens develops and the problems it can cause when left untreated.
    We’ll also walk through actual mesiodens treatment, step by step, including extraction and how the resulting gap is closed with orthodontics.

    mesiodens

    What Is a Supernumerary Tooth and a Mesiodens?

    A supernumerary tooth is an extra tooth that develops beyond the normal count of 32, and when it appears between the upper front teeth at the midline, it’s called a mesiodens.

    Most people have felt self-conscious about crooked teeth whenever they smile.
    But spotting an unexpected extra tooth between the front teeth raises even more concern.

    Misaligned teeth don’t just affect appearance — they can directly impact overall dental health.

    mesiodens case image 3

    Key Points
    ✅ Studies report that mesiodens occurs in roughly 0.3–0.8% of children in the primary dentition stage.
    ✅ In the permanent dentition stage, that rate is reported to rise to 1.5–3.5%.
    ✅ It is reported to occur about twice as often in males as in females.

    mesiodens case image 4

    mesiodens case image 5

    Statistically, mesiodens is notably more common in males.
    Both domestic and international studies report a male-to-female ratio of roughly 2 to 1.

    If a mesiodens is found, it’s important to first accurately assess its position, orientation, and relationship to neighboring teeth.

    mesiodens case image 6

    Key Characteristics of Mesiodens: Checklist
    ✅ Occurs at the center of the upper jaw, either erupted or impacted
    ✅ About twice as common in males as in females
    ✅ Can block permanent tooth eruption and cause dental misalignment

    What Happens If a Mesiodens Is Left Untreated?

    Leaving a mesiodens untreated can block the eruption path of permanent teeth and put pressure on the roots of neighboring teeth, potentially leading to root resorption.

    When a supernumerary tooth blocks a permanent tooth from erupting, that tooth may fail to come in at its proper position.
    This often disrupts overall tooth alignment and can lead to malocclusion.

    Cyst formation inside the jawbone has also been reported in some cases, so it’s worth watching for.

    mesiodens case image 7

    Things to Watch For
    ⚠️ Ignoring it just because there’s no pain can allow damage to neighboring teeth to progress.
    ⚠️ Treatment differs greatly depending on position and shape, so a thorough exam should come first.

    If the tooth is small and isn’t causing other effects, periodic monitoring alone can sometimes be enough.
    But if it’s causing complications, surgical extraction becomes necessary.

    To address both the leftover space and any malocclusion after extraction, orthodontic treatment is typically needed alongside it.

    mesiodens case image 8

    Mesiodens Treatment Decision Checklist
    ✅ Blocking permanent tooth eruption → Extraction needed
    ✅ Causing dental misalignment or malocclusion → Orthodontic treatment combined
    ✅ Risk of root resorption in a neighboring tooth → Prompt treatment
    ✅ No discomfort and no effect on surrounding teeth → Regular monitoring

    mesiodens case image 9


    How Does Mesiodens Treatment Work After Extraction?

    After mesiodens extraction, orthodontic treatment typically follows to close the gap between the front teeth by moving the upper front teeth backward.

    Take, for example, a patient in their twenties who came in with cosmetic concerns.
    The mesiodens had erupted much like an ordinary tooth, but its shape was abnormal.

    A panoramic X-ray showed a peg-shaped tooth with a short root. Since it wasn’t impacted, extraction was relatively straightforward.

    mesiodens case image 10

    Extracting the tooth leaves an open space between the front teeth.
    Closing that space requires moving the upper front teeth backward.

    But the lower front teeth, which were blocking that movement, also needed to shift for the space to close.
    So the plan called for moving the entire lower dental arch backward.

    To create room in the lower arch, the wisdom teeth were extracted first.
    Orthodontic mini-screws were then placed to move the entire lower arch backward.

    mesiodens case image 11

    Category Condition Before Treatment Treatment Plan and Progress
    Upper jaw (maxilla) Abnormally shaped mesiodens erupted, creating an interdental gap Space closed with orthodontics after extraction of the supernumerary tooth
    Lower jaw (mandible) Insufficient space was blocking movement of the upper arch Wisdom teeth extracted and the entire arch moved backward using mini-screws

    mesiodens case image 12

    Treatment Progress
    ✅ The gap left by extraction gradually closed as orthodontic treatment progressed.
    ✅ As the entire arch moved backward, the previously protruding lower lip line also became more balanced.

    mesiodens case image 13

    Leaving a mesiodens untreated can allow dental misalignment to worsen over time.
    We recommend visiting an orthodontic dental clinic in Cheongnyangni for a thorough examination.

    Getting systematic care at Yonsei Dajeonghan Orthodontic Clinic in Cheongnyangni, where a specialist is on staff, is a sound option.
    Even complex dental issues, when addressed in the right order, may help support a more balanced overall appearance.


    Frequently Asked Questions

    mesiodens case image 14

    1. Does a supernumerary tooth always need to be surgically extracted?
    Surgical extraction is needed when a supernumerary tooth is deeply impacted in the jawbone or causes complications such as blocking permanent tooth eruption or forming a cyst. If it’s small and has no significant effect, however, regular monitoring without extraction may be enough.

    2. Is orthodontic treatment required after mesiodens extraction?
    Orthodontic treatment is generally needed when the extraction leaves a sizable gap or when misalignment and malocclusion have already developed. If the space is left as is, neighboring teeth can tilt into the gap, which may disrupt the entire dental arch.

    3. Is moving teeth backward with mini-screws painful?
    The procedure is done under local anesthesia, so there is little to no pain during the process. It involves placing a small screw into the jawbone through a relatively simple procedure, and it helps move teeth efficiently, which can reduce the likelihood of needing further extractions.

    4. At what age is a mesiodens usually discovered?
    It’s often found during routine checkups around the time permanent teeth are erupting. Some cases are discovered incidentally in adulthood, so regardless of age, a thorough exam is recommended whenever one is found.
