5 Dental Clinics for Cavity Treatment in Jeju: How to Choose Based on Reviews and Ratings

Key Takeaways

If you are a foreign patient visiting a dental clinic in Jeju, note that English-speaking support is not guaranteed. Language assistance varies by clinic and must be confirmed directly by phone or through the clinic's booking page. Always call ahead or check online reservations to verify whether an English-speaking consultation is available. Bring your passport and any dental records if you have them.

When looking for a cavity treatment clinic in Jeju, the publicly available data highlights 연세마음편한치과의원 (Yeonsea Maeum Pyeonhan Dental Clinic) and 이도조은소아치과의원 (Ido Joeun Pediatric Dental Clinic) as strong options. Yeonsea Maeum Pyeonhan Dental Clinic stands out with 409 Naver reviews and a Kakao rating of 4.8, while Ido Joeun Pediatric Dental Clinic shows a Kakao rating of 5.0 with 81 Kakao reviews, indicating high satisfaction for children’s care. For adult cavity treatment, the clinic with the most reviews — Yeonsea Maeum Pyeonhan — is a prime candidate; for children, Ido Joeun Pediatric Dental Clinic is especially worth comparing. By ratings alone, Jeju Gouni Dental Clinic (제주 고운이치과의원) also scores a respectable 4.5 on Kakao.

However, cavity treatment decisions should go beyond simple ratings. Factors such as office hours, appointment availability, parking, and the specific treatment needed all matter. For mild cavities, amalgam or glass ionomer fillings are covered by insurance and cost KRW 10,000–30,000; resin fillings for permanent teeth in children 12 and under are covered at about KRW 20,000–50,000. Adult resin fillings are not covered and cost KRW 80,000–150,000, inlays KRW 250,000–500,000, and crowns KRW 350,000–800,000 depending on the material.

Analysis Method

This comparison is based on 635 Naver Place visitor reviews, 162 KakaoMap reviews, and Health Insurance Review & Assessment Service (HIRA) registration data. We collected and reviewed these sources, then compared the public data of five selected clinics. For each clinic, we checked the number of reviews across platforms, public ratings, office hours, parking availability, and the treatment departments and equipment registered with HIRA. Because exposure varies by platform, the safest approach is to consider both total reviews and individual platform ratings together. The information below is limited to what was actually found in the collected data.
