Checklist for choosing a cavity treatment dental clinic
- Examination results — Ask to have the teeth with cavities, the extent, and the basis for the examination explained.
- Treatment options — Ask what treatments are possible depending on the tooth condition and how each method differs.
- Tooth preservation — Discuss how much tooth structure would be removed and whether the tooth can be preserved.
- Materials and costs — Check the cost by material and whether it is covered by insurance or not.
- Additional costs — Ask whether there are separate costs for examinations, temporary treatment, or other items.
- Provider information — Check HIRA-registered specialist information and who will actually provide the treatment.
- Treatment schedule — Ask about the number of visits, intervals between visits, and whether evening or weekend care is available.
- Booking and waiting — Check how to book and whether same-day care is possible.
- Parking and location — Check parking conditions and the actual walking route from the station exit to the clinic.
Warning signs
- When they rush you to decide on treatment without fully explaining the examination results or why treatment is needed
- When they do not clearly explain the treatment materials, scope, or costs, or do not answer your questions
- When it is difficult to confirm the treatment options and how each method differs
- When they definitively promise treatment effects or results based only on online reviews
These items are things to check during a consultation. Judgments about a specific medical institution's actual treatment practices cannot be made from public reviews alone.
