What to expect at Isu Yonsei Baro
The first visit takes about 60 minutes and covers digital intraoral scans, X-rays or 3D CT, photos and an examination by Dr. Sally Chaekyung Lee. She explains findings, options and a typical timeline in English and gives you a written estimate.
Dr. Lee is a Ministry of Health and Welfare certified orthodontic specialist with a PhD in Orthodontics from Yonsei University, and she personally handles every visit from consultation to retention. The clinic uses NovaCare, a device intended to reduce orthodontic discomfort.
In Dr. Lee's practice, patients who want to fix only crowding or spacing in the front teeth are first checked to see whether limited treatment is realistic for their bite, rather than assuming full treatment is needed. Individual results and side effects vary; treatment is decided after examination.
English paperwork
English receipts, itemized statements and medical certificates are available on request, and complete English records can be prepared if you move abroad during treatment.
