Orthodontic Clinic Selection Checklist
- Whether an orthodontic specialist is on site — Check whether a specialist in orthodontics registered with the Health Insurance Review and Assessment Service directly provides treatment
- Precision diagnostic equipment such as cone-beam CT — Confirm whether 3D CT is available for accurate analysis of tooth position
- Orthodontic experience and case history — Ask during consultation whether the clinic has extensive experience treating similar malocclusions
- Transparency in treatment duration and cost — Check whether the expected treatment period and total cost are clearly explained
- Regular checkups and emergency response — Confirm whether the clinic can respond quickly if problems arise during treatment
- Accessibility and parking — Consider transportation and parking convenience for long-term follow-up visits
- Clinic hours — For office workers, check whether evening or weekend visits are available
- Real patient reviews and satisfaction — Review detailed orthodontic treatment feedback in online reviews
- Aftercare and retainers — Check the retainer management and regular follow-up system after treatment is complete
Warning Signs to Watch For
Excessive discounts and low-price marketing: Orthodontic treatment that is far cheaper than normal market prices may have quality issues. Since orthodontics is a long-term, precision medical service, a reasonable price should be maintained.
Immediate treatment recommendations without consultation: Avoid places that recommend same-day appliance placement without enough examination and consultation. Proper orthodontic treatment requires time for detailed examination and treatment planning.
Unclear specialist information: Be cautious if the doctor’s specialty or experience is not clearly disclosed, or if a general dentist rather than an orthodontic specialist is handling the treatment.
Lack of aftercare system: It is best to avoid clinics where the response plan for broken appliances or emergencies is unclear, or where the medical staff changes frequently during treatment.
