The right treatment, at the right time

Dr. Lee previously led pediatric and adolescent orthodontics at CDC Children's Dental Clinic in Cheongdam. She checks how your child's jaw is growing and how the teeth are coming in before deciding whether to treat now or wait.

When to come in

A first check by age 7

The American Association of Orthodontists recommends an orthodontic check-up by age 7. Many children will not need treatment yet, but a few problems are much easier to guide while the jaw is still growing.

Signs worth a check

  • New front teeth coming in crowded or twisted
  • Lower teeth in front of the upper teeth
  • Upper front teeth that stick out
  • Mouth breathing, thumb sucking or tongue thrusting
  • Baby teeth lost much earlier or later than usual
  • The jaw shifting to one side when biting

Approaches

Treatment depends on your child's stage

Monitoring

Regular check-ups when the best move is to wait for more teeth to come in.

Habit and functional appliances

Help correct habits like thumb sucking or tongue thrusting that affect growth.

Growth guidance

Appliances that use growth to improve how the jaws develop.

Space management

Holds or creates room so permanent teeth can come in properly.

We assess skeletal maturity from X-rays to time treatment to your child's growth stage.

Questions

Children's orthodontics FAQ

When should treatment start?
Usually during the mixed-dentition years, when front permanent teeth are coming in alongside baby teeth. The right moment is set after a check-up.
Can my child have treatment while baby teeth remain?
Yes. Some treatment works best at this stage, for example guiding jaw growth or keeping space for permanent teeth.
Does every child need early treatment?
No. Many children only need monitoring. Dr. Lee recommends early treatment only when waiting would make the problem harder to fix.
Will early treatment mean no braces later?
Not always. Early treatment can make later treatment shorter or simpler, and some children still need a second phase as teenagers.
How long does it take?
It depends on the appliance, the goal, your child's growth and how well they wear it. You will get a timeline after the check-up.
