Orthodontic Clinic Selection Checklist
- Presence of an orthodontic specialist — Check whether an orthodontic specialist certified by the Health Insurance Review and Assessment Service personally provides treatment
- Cone-beam CT equipment — Verify whether the clinic can create precise orthodontic treatment plans using 3D imaging
- Before-and-after case disclosure — Check whether real orthodontic results are transparently shared on the blog or Instagram
- Evening and weekend hours — For office workers or students, confirm whether evening or weekend appointments are available
- Transparent total treatment period and cost — Confirm whether the clinic clearly explains the full treatment plan and total cost during consultation
- Emergency response system — Check whether the clinic can respond quickly if an emergency occurs during orthodontic treatment
- Parking and public transportation accessibility — Since orthodontic care requires regular long-term visits, transportation convenience matters
- Ability to coordinate with other treatments — Check whether cavity treatment, extractions, implants, and other needed procedures can be handled in one place before and after orthodontics
Warning Signs to Watch For
Excessive discount promotions: It is best to avoid clinics that offer prices far below normal orthodontic treatment fees and pressure you to sign a contract the same day.
Treatment by general dentists only, without a specialist: If orthodontic treatment is performed by a general dentist rather than an orthodontic specialist, the quality of the final result may be lower.
Unclear treatment plan: Clinics are difficult to trust if they do not clearly explain the total treatment period, step-by-step process, and expected costs, and only give vague answers.
Suspicious review manipulation: If many similarly worded positive reviews are posted in a short period, you should suspect the possibility of fake reviews.
