Key Takeaways
Foreign residents and medical tourists should know that language support varies from clinic to clinic in Yongin, and the public data used in this article does not state whether any of the five clinics below offers English-speaking staff — confirm by phone or on the clinic's own booking page before you visit. Booking is usually done by phone (each clinic's number is listed below), and it helps to bring your ARC or passport, a list of any medications you take, and previous dental X-rays or treatment records if you have them.

How We Analyzed the Data
The data collected consists of 6,660 Naver Place visitor reviews, 3,102 KakaoMap reviews and Health Insurance Review & Assessment Service (HIRA) registration data. The average KakaoMap rating of the five selected clinics is 4.9. For each clinic we compared the Naver, Kakao and Google review counts and ratings provided, the address, opening hours, access, amenities and HIRA information. "Total reviews" in the table is the sum of the Naver visitor reviews, Kakao reviews and Google reviews listed in each clinic's data, counted by platform. Duplicate posting across platforms has not been verified, so it does not represent unique visitors or a de-duplicated review count. Naver ratings were not included in the source data, so they are shown as "not available". Reviews are individual experiences and are not grounds for concluding anything about a clinic's treatment outcomes.

Checklist for Choosing a Cavity Treatment Clinic
- Basis for the cavity diagnosis — ask which examinations and observations led to the recommended treatment.
- Extent of treatment — confirm specifically which teeth need treatment, how much, and in what order of priority.
- Treatment options — have the possible materials and methods, and the differences between them, explained to you.
- Total estimated cost — ask separately about covered versus non-covered items and about examination and material costs.
- Possible further treatment — check whether additional treatment may be needed given your current condition.
- Schedule — confirm the number of visits, available appointment times and the follow-up plan after treatment.
- Specialist information — if the number of specialists matters to you, check HIRA registration data and the clinic's own information.
- Parking and transport — check parking availability and conditions and your public transport route before visiting.
- Hours and closures — lunch hours and holiday or Sunday opening may not be in the provided information, so confirm by phone.
Warning Signs to Watch For
The points below are not an assessment of any particular clinic but general items to check during a consultation.
- If you are pushed to decide on treatment quickly without an explanation of your decay status or why treatment is needed, go back over the examination results and the reasoning.
- If you ask about the cost of each treatment option or about covered versus non-covered items and get no specifics, ask for the costs item by item.
- If the extent of treatment, the expected number of visits and aftercare instructions are not explained well enough, ask for more detail.
- Do not conclude anything about treatment outcomes from online ratings or reviews alone. Each person's dental condition and treatment plan can differ.
Frequently Asked Questions
What should I compare first when choosing a cavity treatment clinic in Yongin?
First look at the distance from home or work, the opening hours, and whether reservations and parking are available, then check the basis for the cavity diagnosis, the treatment options and the cost during the consultation. The reviews and ratings in this article are reference information.

How much does cavity treatment cost?
As reference information, amalgam and glass ionomer are covered at KRW 10,000–30,000, and resin on permanent teeth for children aged 12 and under is covered at about KRW 20,000–50,000.

Actual costs vary with the condition of the tooth and the treatment provided, so confirm with the clinic.
Can I get an English-speaking consultation at these Yongin dental clinics?
The public data used in this article does not state which languages any of the five clinics can handle, so English-speaking support cannot be confirmed in advance from these listings. Call the clinic directly (for example, 0507-1472-2298 for Yonsei On Dental Hospital's Yongin branch) or check its own booking page, and ask whether an English-speaking dentist or coordinator is available on the day you want to visit. If not, consider bringing a Korean-speaking friend or an interpreter app, and ask for the treatment plan and cost estimate in writing.
If the number of dental specialists is "not available", does that mean there are no specialists?
No. It means the number of specialists registered with HIRA could not be confirmed in this data. Whether a specialist is present cannot be determined from this, so check with the clinic or with HIRA information separately.
If a clinic has high review ratings, does that mean its cavity treatment results are good?
Ratings are reference information summarizing the experiences of review writers and do not guarantee treatment outcomes. Have your own dental condition diagnosed, discuss the basis for treatment, the alternatives and the cost, and then decide.
