Frequently Asked Questions
Why is an orthodontic specialist important?
An orthodontic specialist is a doctor who completed 4 years of additional training after dental school graduation and received certification from the Ministry of Health and Welfare. Only 1.5% of all dentists are orthodontic specialists. Especially during the long 2-3 year treatment period, it's important that one specialist is responsible from start to finish without changing doctors.
How much does orthodontic treatment cost?
Orthodontic costs vary depending on individual tooth condition, chosen treatment method, and expected treatment duration. Exact costs will be provided after precise diagnosis during consultation, and interest-free installments are available.
How long does orthodontic treatment take?
Generally 18-30 months. This varies by individual tooth condition and treatment goals, with exact duration provided after precise diagnosis. Even after braces removal, wearing retainers is important to maintain orthodontic results long-term.
Is orthodontics very painful?
You may feel some tightness for a few days after initial bracket placement or adjustments, but most people adapt quickly. Self-ligating brackets and clear aligners cause less pain than traditional brackets for more comfortable treatment.
Can adults get orthodontic treatment?
Yes, of course. Orthodontics is possible regardless of age. Even those in their 40s and 50s can have a beautiful smile. However, adults experience slightly slower tooth movement than growing children, and gum health should be checked first. Many prefer clear aligners or lingual braces for aesthetics.
Is tooth extraction always necessary?
Not all patients require extraction. It depends on tooth alignment, protrusion level, and space shortage, with extraction necessity determined after precise diagnosis. While non-extraction is preferred when possible, extraction may be necessary for better results.
Is Invisalign effective?
Yes, it's effective. However, it's not suitable for all cases. It's recommended for minor alignment issues or those who prioritize aesthetics, while complex cases may benefit more from bracket orthodontics. Dr. Seungmin Ryu has completed official Invisalign training for professional clear aligner treatment.
When should my child start orthodontics?
First orthodontic checkup is recommended at ages 6-7. Detecting problems early at this age allows effective orthodontics utilizing growth. Actual orthodontic treatment usually begins after age 9-10, but optimal timing varies by individual, so accurate diagnosis by an orthodontic specialist is important.
