Bite
The jaws look misaligned
Mouth movements look unnatural when the child chews or speaks.
A baby tooth and its permanent successor
In growing children, tooth eruption, bite and jaw development are assessed together. Some problems may benefit from treatment during growth, while others are monitored before a decision is made. This care needs regular in-person visits over an extended period, so it suits families living in Korea or staying long term.

Children's orthodontics at a glance
Children's orthodontics assesses developing concerns such as crossbites, crowding after early baby-tooth loss and jaw relationships. The clinician considers the child's growth and eruption stage before recommending treatment or continued observation. Headgear, face masks and activators are different options selected for specific needs, not a sequence every child follows.
- Growth-stage appliances
Headgear, face mask, activator. Which one depends on the direction of growth.
- Best suited to
Families based in Korea or staying long term. Not a short medical-travel treatment.
- Treatment window
Timing depends on tooth eruption, the bite and the child’s growth stage. Assessment may lead to treatment or continued observation.
- What it does not promise
That braces will never be needed later. Some children still need a second phase.
Concerns this page answers
These are the reasons parents most often bring a child in. An examination decides whether to treat now, monitor, or wait.
Crowding
Baby teeth were lost early
Cavities took the baby teeth early and the permanent teeth are coming in crooked.
Space after early baby-tooth loss
Lower jaw
The lower face looks more prominent
If the lower face appears more prominent as your child grows, an examination can assess the bite and the relationship between the upper and lower jaws. Appearance alone does not determine the growth pattern or the treatment needed.
Gums
The front teeth hit each other
The upper and lower front teeth collide and the gums are starting to recede.
When front tooth edges meet
Final treatment plan, cost and duration are confirmed after in-clinic diagnosis.
Assessment, a tailored plan and follow-up
Three parts of care, with timing guided by each child's development. Assessment may lead to treatment or continued observation.
Step 1
Assess growth, eruption and the bite
The clinician examines tooth eruption, tooth positions, the bite and jaw development. These findings inform whether treatment or observation is appropriate.
Assessing the bite and jaw relationship
Treatment when appropriate
Growth
Some developing bite problems may benefit from treatment during growth. The appliance and timing are chosen after assessing the child's bite and growth pattern.
Continued observation
Timing
An assessment does not always mean treatment starts immediately. Some children are monitored with regular reviews until treatment is appropriate.
Step 2
Choose the timing and an individual plan
If treatment is appropriate, the clinician discusses the appliance and timing for the child's bite and growth pattern. An assessment does not mean every child starts treatment immediately.
Step 3
Review progress as the child grows
Regular reviews check growth, tooth eruption and treatment progress where treatment has started. Dental concerns are assessed along the way, and the plan is reviewed as the child develops.
Teeth, growth and treatment timing
Planning considers tooth positions and jaw development. The clinician assesses whether treatment or observation is appropriate while growth continues.
Teeth
An appliance can apply controlled forces to move teeth. This illustration explains tooth movement; it does not show how an appliance guides jaw growth.

Appliances considered for different bite problems
These are options, not consecutive treatment steps. Assessment of the bite and growth pattern determines whether an appliance is appropriate and when it may be used.
Assessed for selected bite problemsHeadgear
A clinician may consider headgear for selected bite problems after assessing the teeth and jaws. Its use and wear instructions depend on the individual plan.
Headgear: bow and padded support
Upper jaw and tooth positionFacemask
A facemask applies forward pull to the upper jaw and teeth. The clinician assesses whether this approach is appropriate for the child's bite.
Facemask supports and upper attachment
Prominent upper front teethActivator (functional appliance)
An activator is one type of functional appliance. These appliances may be considered for growing patients whose upper front teeth sit ahead of the lower teeth. The clinician assesses suitability and explains what changes can reasonably be expected.

Wearing the appliance, and what to expect
First weeks
Getting used to it
- Speech and eating feel different for a while.
- Mild soreness after an adjustment is common and settles.
- Removable appliances only work for the hours they are actually worn.
During treatment
Cavities are watched at the same time
- Appliances make brushing harder, so cavity risk goes up.
- Dental problems that arise are handled alongside the orthodontic work.
- Eruption is rechecked at each visit, not only at the start.
Care for a removable appliance
After the appliance
The result has to be held
- Teeth drift back if nothing holds them.
- A retainer is part of the treatment, not an optional extra.
- Some children still need an alignment phase after the permanent teeth come in.

An honest note for international families
Children's growth-stage orthodontics is not a one-trip treatment. Appliances must be adjusted as the child grows, which means regular in-person visits over months to years. We recommend it for families residing in Korea or staying long term.
If you are visiting briefly, we can examine your child and share findings you can take to a local orthodontist, but we will not start a treatment we cannot properly supervise.

Before an appliance is chosen, we confirm
- Board-certified specialists diagnose and manage cases together, so a child's plan is reviewed with eyes on cavities, eruption and gum health - not orthodontics in isolation.
- Treatment is paced to each child's own growth rather than to a fixed schedule.
Questions parents ask
At what age should my child first see an orthodontist?
There is no single right age - it depends on the problem. An examination will tell you whether to treat now, monitor, or wait.
We are an expat family in Korea. Can our child be treated here?
Yes - families living in Korea are exactly who this treatment suits. If you may relocate mid-treatment, tell us at the consultation: we will plan phases accordingly and prepare records for a smooth handover to an orthodontist in your next country.
Will early treatment mean my child never needs braces later?
Not necessarily, and we will not promise that. The benefit of the early phase is creating better conditions - it does not guarantee that a second phase will never be needed.
How often will we have to come in?
Often enough that the appliance keeps pace with growth, over months to years. The exact interval is set after the growth assessment, since children grow at different speeds.
What if my child will not wear a removable appliance?
Tell us early. A removable appliance only works for the hours it is actually worn, so if wear time is unrealistic we would rather change the plan than let the treatment drift.
