Checklist for choosing a cavity-treatment dental clinic
- HIRA specialists and departments — If the cavity is deep, check whether conservative dentistry is publicly listed.
- Ratings and review counts — Even if the rating is 5.0, a small number of reviews means less reliable signal. 124 Kakao reviews and 973 Kakao reviews should be weighed differently.
- Direct cavity-treatment reviews — Prioritize real reviews that mention cavity treatment, root canals, or resin fillings.
- Possibility of root canal treatment — If the cavity has reached the nerve, ask about the stages and expected number of visits during consultation.
- Publicly listed equipment — If cone beam CT or similar equipment is shown in HIRA data, it can help with assessing your tooth condition.
- Location and access — Check whether the walk from the station exit is short and whether it fits your route.
- Hours — If you work during the week, check whether the clinic stays open after 20:00 on Mon/Wed/Thu.
- Amenities — Check whether parking, reservations, waiting space, and Wi-Fi are listed.
- Parking capacity and booking method — Even if parking is listed, you should confirm the number of spaces by phone.
- Cost confirmation — Cavity-treatment fees can vary by clinic, so confirm the exact price by phone.
Warning signs to watch for
- If a clinic has a 5.0 rating but fewer than 10 reviews on a channel, or if the reviews are clustered on only a few dates, read the full reviews carefully.
- If the clinic tries to move straight to major treatment without explaining the X-ray findings for the cavity, consider getting a second consultation.
- If no HIRA department or specialist information is publicly available but the clinic keeps calling itself a specialist clinic, verification is needed.
- If reviews repeatedly exaggerate treatment outcomes, such as pain disappearing instantly or being cured on the same day, be cautious.
