Key Takeaways
If you are a foreign resident or medical tourist in Korea, the practical starting point is finding out whether an English-speaking dental clinic in Gangdong-gu (강동구) can handle your consultation. Language support varies from clinic to clinic and is not shown in the review data below, so confirm it by phone or through the clinic's website or booking page before visiting. Do not assume English is available from ratings or reviews alone. Bring a passport or Alien Registration Card and, if you have Korean health insurance, bring your insurance card as well.
Looking at the collected data alone, 서울안아프게치과의원 (Seoul An-apeu-ge Dental Clinic) and 센트럴뉴욕치과의원 (Central New York Dental Clinic) stand out first. The former has a Kakao rating of 5 with 231 Kakao reviews and a Google rating of 4.9 — the highest score here. Central New York has the largest review base, with 1,093 Kakao reviews, a 4.3 Kakao rating, and a 3.7 Google rating. The five selected clinics have an average KakaoMap rating of 4.7. In actual visitor reviews, words like kind, careful explanation, and "no excessive treatment" appeared repeatedly.
Cavity treatment cost depends on the extent of treatment and the material used. Amalgam and glass ionomer are covered by national health insurance at about KRW 10,000 to 30,000. Resin is covered only for permanent teeth in children aged 12 and under, at about KRW 20,000 to 50,000; for adults, resin is non-covered and typically ranges from KRW 80,000 to 150,000. An inlay can cost KRW 250,000 to 500,000, and a crown can range from KRW 350,000 to 800,000 depending on the material. In a consultation, confirm both your tooth condition and the material options.
How We Analyzed
This comparison was prepared by checking 0 Naver Place visitor reviews, 1,326 KakaoMap reviews, Google reviews, and registration data from the Health Insurance Review and Assessment Service (HIRA). The average KakaoMap rating of the five selected clinics is 4.7. For each clinic, we compared platform ratings, review counts, accessibility, treatment hours, facilities, and actual visitor reviews. Where the collected data did not include the number of dental specialists, it is marked as not available.
1. 서울안아프게치과의원 (Seoul An-apeu-ge Dental Clinic)
Why it stands out: It has a Kakao rating of 5, a Google rating of 4.9, and 231 Kakao reviews. The number of dental specialists is marked as not available in HIRA data. Reviews repeatedly mention treatment designed to reduce pain and considerate consultation.
We decided to have two teeth pulled over two visits, but it hurt less than I expected. When I went back for the other side, I was not too worried. Haha, I trust the director.
I am pregnant and had been putting off a cavity until I could not stand it anymore. They treated me safely once I was in a stable period. Thank you, I feel alive again.
Location and transit: 538m from Exit 5 of Cheonho Station (천호역 5번 출구). Hours: Monday 09:30-20:30, Wednesday 09:30-20:30, Friday 09:30-18:30, Tuesday 09:30-18:30, Saturday 09:30-14:30, Sunday 09:30-14:30. Lunch break information was not in the collected data.
Before you go: Confirm whether reservations are available, whether parking is available, and facilities such as a waiting area, Wi-Fi, and easy payment. Website, blog, and Instagram information are all available, so pre-visit checks are relatively easy.
Practical tip: If you suspect a cavity, book a consultation before the pain gets worse. As the pregnant-patient review shows, your situation may require adjusting the timing of treatment, so tell the clinic about your condition when you make the appointment.
Cavity treatment notes: Extraction and implant cases appear in this clinic's reviews, but actual cavity treatment costs depend on the size of the lesion and the material. Adult resin is non-covered and typically ranges from KRW 80,000 to 150,000. Whether an inlay or crown is needed is decided after diagnosis.
2. 센트럴뉴욕치과의원 (Central New York Dental Clinic)
Why it stands out: It has the largest review base, with 1,093 Kakao reviews. Its ratings are 4.3 on Kakao and 3.7 on Google. The dental specialist count is marked as not available. Because of the large number of reviews, this clinic has a substantial base of real patient experiences.
I booked at Central New York Dental Clinic and was taken in immediately. The doctor was thorough and made the scaling comfortable. If you are looking for a dental clinic in Gangdong-gu, I would recommend this place.
A local resident recommended this clinic, and I have never had a place explain things this carefully. Everyone stayed late because of me, but they were kind from beginning to end. I have found my regular dental clinic.
Location and transit: 50m from Exit 2 of Cheonho Station (천호역 2번 출구), so it is very close to the station. Hours: Monday, Tuesday, Wednesday, and Friday 10:00-19:00; Saturday 10:00-14:00. Thursday treatment hours were not confirmed in the data. Lunch break information is not available.
Before you go: Confirm reservation availability, parking, Wi-Fi, and separate male and female restrooms. Website, blog, and Instagram information are available, so pre-visit information is easy to check.
Practical tip: This clinic is very convenient for people who prioritize public transportation access. Since several reviews mention detailed explanations, allow enough time for the consultation, especially because cavity treatment involves material and cost choices.
Cavity treatment notes: Adult resin is non-covered and typically ranges from KRW 80,000 to 150,000. An inlay can cost KRW 250,000 to 500,000, and a crown can cost KRW 350,000 to 800,000. The actual cost depends on the depth and extent of the cavity.
3. 서울프라임치과의원 (Seoul Prime Dental Clinic)
Why it stands out: It has 30 Google reviews, and the review text repeatedly mentions kindness and no excessive treatment. Kakao and Naver reviews are 0 in the collected data, and no separate rating score was collected. The dental specialist count is marked as not available.
I booked only a checkup and consultation, and I was seen right away. Everyone was kind and good.
I booked a national health insurance scaling appointment and was seen immediately. A coworker recommended this place, and just as expected, there was no excessive treatment. They were kind, and they carefully re-examined me to answer every question. Thank you.
Location and transit: Location and transit information was not in the collected data, so it is safer to confirm by phone or the clinic's homepage before visiting. Hours: Monday through Friday 09:30-18:30. Saturday and Sunday treatment hours are not available, and lunch break information is not available.
Before you go: Confirm reservation availability, parking, and separate male and female restrooms. One review mentions that the clinic is inside the Samsung building, but reconfirm the building location and route before your visit.
Practical tip: The review pattern fits people who want to combine a regular checkup or scaling with a cavity examination. Some reviews mention checking before-and-after photo records, so ask how treatment records and photos are managed during the consultation.
Cavity treatment notes: The review flow suggests a consultation-first approach before deciding on cavity treatment. For a small cavity, check the covered amalgam or glass ionomer range of KRW 10,000 to 30,000. For adult resin, the non-covered range of KRW 80,000 to 150,000 is a good starting point.
4. 서울원치과의원 (Seoul One Dental Clinic)
Why it stands out: It has a Google rating of 3 and 3 Google reviews, but the review text generally mentions kindness and no excessive treatment. The number of reviews is small, yet some reviews describe visiting over many years, which shows regular-patient experience. The dental specialist count is marked as not available.
For a visit without an appointment, I was treated quickly, and I was satisfied because there did not seem to be any excessive treatment. This is a clinic I would recommend to acquaintances.
I have been going here for six years for orthodontics, implants, cervical wear, wisdom tooth extractions, and more. The director is always kind and careful.
Location and transit: 92m from Exit 1 of Amsa Station (암사역 1번 출구), so it is also very close to the station. Hours: Monday 09:30-18:30, Tuesday 09:30-20:30, Wednesday 09:30-17:00, Thursday 09:30-20:30, Friday 09:30-18:30, Saturday 09:30-13:30. Sunday treatment is not listed in the data, and lunch break information is not available.
Before you go: Confirm appointment availability and expected waiting time. One review says that even without an appointment, treatment was relatively quick, but congestion can vary by time of day. Facility information was not in the collected data.
Practical tip: If you work during the day, the Tuesday and Thursday evening hours until 20:30 are useful. You can plan a visit to have a scaling and ask for a cavity check at the same time.
Cavity treatment notes: As the cavity becomes larger, an inlay of KRW 250,000 to 500,000 or a crown of KRW 350,000 to 800,000 may be needed. If the cavity is early-stage, ask during the consultation whether covered treatment is possible first.
5. 유디천호치과의원 (UD Cheonho Dental Clinic)
Why it stands out: It has 2 Kakao reviews and 4 Google reviews, so the volume is small, but the review text contains phrases such as no excessive treatment, finished in one visit, and did not hurt. Its Google rating is 2.5. The dental specialist count is marked as not available.
First appointment, booked in advance, and I was in the treatment room within 10 minutes. Clean and spacious. I had a scaling done. This clinic does not do unnecessary things. It is the first dental clinic I have been to where they tell you to come back if it hurts. That is a good thing.
I booked a scaling and was seen right away. I used to go to a different dental clinic, but I have been coming to UD Cheonho Dental Clinic for three years. I like that they finish everything in one visit. Kindness and a comfortable environment are basic here.
Location and transit: 325m from Exit 3 of Gangdong-gu Office Station (강동구청역 3번 출구). Hours: Monday through Friday 09:30-18:30, Saturday 09:30-14:30. Sunday treatment is not listed, and lunch break information is not available.
Before you go: Confirm reservation availability and parking. In the facility data, only reservation and parking are confirmed. Since many reviews mention scaling, this clinic may be useful if you want a cavity diagnosis along with a gum check.
Practical tip: If you want a short checkup and only necessary treatment, clearly confirm the treatment scope during the consultation. Cavity treatment costs differ greatly depending on whether the cavity is early-stage or requires root canal treatment.
Cavity treatment notes: For early-stage cavities, first check the covered amalgam or glass ionomer range of KRW 10,000 to 30,000 and the non-covered adult resin range of KRW 80,000 to 150,000.

Checklist for Choosing a Cavity Treatment Dental Clinic
- Review volume - Do not look only at the average rating; check how many real visitor reviews exist.
- Rating source - Separate ratings by platform: Kakao, Google, Naver, and so on.
- Evening hours - Check whether the clinic is open on weekday evenings.
- Distance from the station - Cavity treatment may require a return visit, so accessibility matters.
- Reservation method - Confirm whether appointments are required or walk-ins are accepted.
- Parking - If you are driving, this is essential.
- Reviews about excessive treatment - Look for whether the clinic explained options and gave enough time.
- Treatment material - Ask whether resin, inlay, or crown is needed.
- Cost explanation - Ask how covered and non-covered treatment are separated.
- Pain management - Ask how the clinic reduces pain during anesthesia and treatment.
Warning Signs
First, if an expensive material or a large treatment is recommended immediately without explanation, ask another question before agreeing.
Second, if reservation and waiting guidance are unclear, treatments that may require a return visit, such as cavity treatment, can become inconvenient.
Third, if the cost breakdown is vague and there is no explanation of covered versus non-covered treatment, confirm it before treatment begins.
Fourth, if the reviews show repeated complaints rather than praise for kindness, or if lack of explanation is mentioned often, compare other clinics before deciding.
