Who do we treat?

Orthodontic needs change with age. A seven-year-old with a crossbite, a teenager with crowded canines and an adult whose teeth have drifted since braces each need a different approach. Dr. Lee plans around where you are in growth and in life, not around a single appliance.

Children (about 6–12)


While the jaws are still growing, some problems are easier to guide than to correct later, and sometimes the right answer is to monitor. Dr. Lee, a mother herself and former director of pediatric and adolescent orthodontics at CDC Children’s Dental Clinic, explains when to act and when to wait.

Teenagers (about 12–18)


Once most permanent teeth are in, full treatment with braces or clear aligners is common. Monday and Thursday evening hours and Saturday mornings help teenagers avoid missing class.


Teen orthodontics →

Adults


Teeth can be moved at any age when the gums and bone around them are healthy. Dr. Lee had orthodontic re-treatment herself in her thirties, so she understands adult concerns about work, appearance and time.

Which appliance is right for you?

Clear aligners and fixed braces can both move teeth precisely. The right choice depends on the movements your teeth need, your bite, how consistently you can wear a removable appliance and your daily routine. Because Dr. Lee offers both, her recommendation follows the diagnosis rather than a preferred product. For a side-by-side view, read braces vs clear aligners .

What bite and alignment problems do we treat?

Orthodontics treats more than crooked teeth. Before recommending anything, Dr. Lee looks at the teeth, bite, roots, jaw bones and the whole face. Problems we commonly see include:



Browse all conditions we treat , or see how three cases were planned in our before and after gallery , published with each patient’s consent.

What happens at your first orthodontic visit?

The first examination takes about 60 minutes: an intraoral digital scan (no impression putty), X-rays or a 3D CT scan, photographs and a full examination by Dr. Lee. For children, a skeletal-maturity analysis helps time treatment. Dr. Lee then explains the diagnosis, your options, an estimated timeline and a written estimate. Bring your passport or Residence Card and any previous X-rays, records or retainers. See the orthodontic treatment process and the diagnostic technology we use .

How are orthodontic fees set?

Fees depend on the complexity of the problem, the appliance and the expected length of treatment, so we do not quote prices before an examination. Orthodontics is generally not covered by Korea’s National Health Insurance, except treatment linked to specific congenital conditions such as cleft lip and palate. Read how orthodontic fees are set .

Orthodontics for international patients

If you are in Seoul for a fixed term, tell us your expected stay and Dr. Lee will plan around it. If you leave before treatment ends, we prepare English records, 3D scans in standard formats and progress notes, and can contact your next orthodontist directly. See moving during treatment and English receipts for insurance claims .

Orthodontics FAQs

  • Will the same orthodontist treat me from start to finish?

    Yes. Dr. Sally Chaekyung Lee handles your consultation, treatment plan and every adjustment herself, through to the end of active treatment. Patients are not passed between doctors for orthodontics, so the person who designed your plan is the one checking its progress at each visit.

  • How do I know whether I need braces or clear aligners?

    It depends on the tooth movements needed, your bite and how consistently you can wear a removable appliance. After the examination, Dr. Lee explains which options would work for you, the trade-offs of each and which she would recommend, so you can decide with full information.

  • When should my child have a first orthodontic check?

    The American Association of Orthodontists suggests a first check by about age 7. Many children seen at that age only need monitoring; the visit tells you whether to wait or act early. Come sooner if you notice a crossbite, constant mouth breathing or a persistent thumb-sucking habit.

  • Can I use private or overseas insurance for orthodontics?

    Some private and overseas policies include orthodontic benefits, so check yours. We do not bill insurers directly, but on request we provide English receipts, itemized statements, medical certificates and doctor’s letters. Ask your insurer which documents it needs before your first visit.

  • Are evening or Saturday orthodontic appointments available?

    Yes. We are open until 9 PM on Mondays and Thursdays and from 9 AM to 2 PM on Saturdays, which helps students and working adults. Tuesdays and Fridays run from 10 AM to 7 PM. We are closed on Wednesdays, Sundays and public holidays.

This page is general information, not a diagnosis. Treatment results and duration vary from person to person. Orthodontic treatment can cause temporary discomfort and, in some cases, root shortening, gum recession or tooth decay if oral hygiene is poor; teeth can relapse if retainers are not worn as instructed.
