Recommended Dental Clinics for Cavities in Ansan: TOP 5 Based on 4,635 Reviews

Key findings first

If you’re looking for a dental clinic in Ansan for cavity treatment, the first places to pay attention to are 연세리더스치과교정과치과의원 안산 (Yeonse Leaders Orthodontics & Dental Clinic Ansan) and 예스플란트치과의원 안산 (Yes Plant Dental Clinic Ansan). They have 1,770 and 697 Kakao Map reviews, respectively, with ratings of 4.4 and 5.0. When Google Maps ratings are included, Yeonse Leaders shows 5.0 and Yes Plant 2.0, but their Google review counts are only 102 and 4, so the Kakao Map data carries more weight here. Both clinics are repeatedly described in reviews as avoiding unnecessary treatment and recommending only what is actually needed for cavity cases. By contrast, 안녕하세요치과의원 has a Google rating of 5.0 and 630 Kakao reviews, but some negative experiences appear in the review data, so a cautious approach is wise.

For foreign residents and medical tourists, the most important practical point is to confirm language support before you go. English-speaking service varies by clinic, so check by phone or on the clinic’s booking page, and bring your ID, insurance card if you have one, and any previous dental records or X-rays.

Detailed clinic analysis

연세리더스치과교정과치과의원 안산 (Yeonse Leaders Orthodontics & Dental Clinic Ansan) - communication-focused care without unnecessary treatment

Why it stands out: 1,770 Kakao reviews, a Kakao rating of 4.4, and a Google rating of 5.0 (102 reviews). It has the largest review base in the comparison, and phrases like “no unnecessary treatment” and “ethical” appear repeatedly. Although it is positioned as an orthodontics clinic, patients seeking cavity treatment and general restorative care also continue to visit regularly.

"넓고 쾌적하고 과잉진료없어서 너무 좋아요! 임플란트as도 친절하게 해주세요!! 진료올때마다 푠하게 해주셔서 감사합니다!!" — 둥이맘조여사, 2026년 8월 3일

"안산에서 교정 치과 여러 군데 돌아다녀 보고 여기로 결정했어용 다른 곳과 다르게 원장님이 치아 각도 하나하나 엄청 세밀하게 봐주십니다. 매번 진료 갈 때마다 불편한 곳은 없는지 먼저 체크해 주셔서 넘 좋았어여" — dhs1301, 2026년 7월 31일

Location: 경기 안산시 단원구 고잔1길 33 봉산빌딩. 396 m from Exit 1 of Central Station on Line 4 / Suin–Bundang.

Hours: Mon 10:00~20:30, Tue/Thu/Fri 10:00~19:00, Wed 10:00~20:30, Sat 10:00~14:00.

Cavity-treatment angle: The doctor’s careful examination is highlighted as a strength. Reviews saying that every tooth angle is examined in detail suggest a precise approach that may be useful for early cavity detection or cavity preparation. The pattern of checking discomfort first suggests a process designed not to miss possible cavity symptoms. Since orthodontic care is the main focus, this clinic may be especially useful for complex cases that need both cavity treatment and alignment planning.

What to check before visiting: Ask by phone how many parking spaces are available. Because this is an orthodontics-focused clinic, it is worth asking whether there may be waiting time if you are coming only for cavity treatment. You should also confirm the booking method and whether English-speaking support is available.

Practical tip: Saturday hours end at 14:00, so if you want a weekend visit, booking early in the day is easier. Monday and Wednesday have evening hours, which is convenient after work.

예스플란트치과의원 안산 (Yes Plant Dental Clinic Ansan) - only the treatment you actually need, even for cavity visits

Why it stands out: 697 Kakao reviews, a Kakao rating of 5.0, and a Google rating of 2.0 (4 reviews). On Kakao, it is close to a perfect score. A representative review says that the patient visited thinking it was a cavity, but only the necessary treatment was explained, which is exactly the kind of feedback many people want to hear. The 5.0 Kakao rating is the only perfect score among the clinics analyzed. The Google score is difficult to interpret because there are only 4 reviews.

"충치인 줄 알고 방문했는데 필요한 치료만 설명해주셔서 부담이 없었습니다. 괜히 겁먹고 갔는데 과잉진료 느낌도 없었고 병원도 깔끔해서 좋았어요ㅎㅎ 주차도 편했습니다!" — 청둥오리물오리52, 2026년 7월 14일

"임플란트 상담 예약 후 이용대기 시간 바로 입장 어금니를 오래 비워두고 있어서 계속 고민만 하다가 상담받게 되었는데요. 무조건 치료를 권하기보다 지금 상태와 치료 시기를 자세히 설명해주셔서 좋았어요." — rkdms8410, 2026년 7월 16일

Location: 경기 안산시 단원구 광덕대로 155 퍼스트빌 2층. In the direction of Exit 2 of Gojan Station on Line 4.

Hours: Tue 09:30~21:00, Wed/Thu/Fri 09:30~18:30, Sat 09:30~13:30.

Cavity-treatment angle: There is a confirmed review pattern showing that patients who came in with suspected cavities were told only what treatment was necessary, with no sense of over-treatment. This suggests a tendency to avoid unnecessary resin or inlay recommendations and focus on the actual treatment range needed. Tuesday evening hours until 21:00 make it the most accessible option for working adults among the clinics analyzed.

What to check before visiting: It is closed on Mondays. Confirm parking capacity and the booking method by phone. Given the Google rating of 2.0, it is also worth checking recent feedback on other review platforms.

Practical tip: Since this is primarily an implant-focused clinic, if you are visiting for cavity care, make it clear when booking that you want a cavity consultation. Tuesday evening slots may be in demand, so early booking is recommended.

안녕하세요치과의원 - high ratings, but mixed reviews

Why it stands out: Google rating 5.0 and 630 Kakao reviews. Based on rating and review count alone, it deserves attention. There are many positive reviews about scaling and extraction, and the keyword “kind” appears repeatedly. However, a closer look shows some serious negative experiences, so consistency is a concern.

"모든 병의원을 통틀어서 최악. 1. 진료 보고자 하는 것 외 부분에 대해서 일방적으로 얘기하여 치료 방법이 뭐냐고 물어보니, 방법이 없어 평생 그렇게 살던가 라미네이트 뿐이라고 권유. (기존에 다니던 치과에서는 치료 시 해결되던 문제) 2. 치아를 확인하면서 망치같은 것으로 치는데 못질과 진배 없음." — 주곰71, 2026년 8월 2일

"직원분들 너무 친절하시고 치료도 잘해주셔서 좋아요~~" — pre****, 2026년 8월 1일

"스케일링도 안아프게 해주시고 너무 친절하세용" — ㅇㄹㅈ1, 2026년 8월 1일

Location: 경기 안산시 단원구 광덕대로 206 2층 207, 208호. 827 m from Exit 2 of Central Station on Line 4 / Suin–Bundang.

Hours: Mon/Tue/Wed/Fri 10:00~18:30, Thu 10:00~21:00, Sat/Sun 10:00~14:00.

Cavity-treatment angle: There are no direct reviews specifically about cavity treatment. Many reviews praise painless scaling and wisdom tooth extraction, which may suggest strength in pain management, but the negative review citing one-sided treatment recommendations means caution is needed when discussing cavity care. Weekend hours are a useful advantage for busy professionals.

What to check before visiting: The detailed service style mentioned in the negative review should be confirmed separately. Ask by phone about parking and whether advance booking is required. Sunday hours end at 14:00, but the reservation process may differ, so it is best to inquire first.

Practical tip: Using Thursday evening hours or visiting on a weekend morning may help reduce waiting time. If you are coming for a cavity consultation, it is wise to prepare in advance in case you want a second opinion after the visit.

안산예치과병원 (Ansan Ye Dental Hospital) - an honest treatment philosophy with 1,517 reviews

Why it stands out: 1,517 Kakao reviews, a Kakao rating of 2.7, and a Google rating of 2.8 (6 reviews). It has the second-largest review volume among the clinics analyzed, but its rating is relatively low. Even so, recent reviews focus on positive words such as “responsibility,” “honesty,” and “a no-frills atmosphere,” so the rating alone does not tell the full story. The reason for the low score cannot be confirmed from the data.

"과장된 수치 없이 딱 제 구강 구조에 맞는 필요한 처치 위주로만 선별해 주는 모습에서 깊은 책임감이 느껴졌습니다" — laki****, 2026년 7월 31일

"예전에 왼쪽 받고 괜찮아서 이번엔 오른쪽 마저 하러 재방문한 건데 변함없이 한결같이 정직하게 봐주시네요" — euna****, 2026년 7월 30일

"이 빠진 채로 오래 둬서 걱정 태산이었는데 뼈 상태 분석 철저하게 하시고 든든하게 계획 세워주셔서 안도감이 들었음ㅠㅠ" — yoju****, 2026년 7월 28일

Location: 경기 안산시 단원구 고잔2길 59 신세기빌딩 2층. 321 m from Exit 1 of Central Station on Line 4 / Suin–Bundang.

Hours: Mon/Thu/Fri 09:30~18:30, Tue/Wed 09:30~20:30, Sat 10:00~14:00.

Cavity-treatment angle: There are no reviews directly mentioning cavity treatment. However, the repeated pattern of selecting only the necessary treatment for a patient’s oral structure suggests a conservative and careful approach to evaluating cavity extent. The existence of return-visit reviews indicates a decent level of patient retention. Because weekday hours start at 9:30 a.m., it may suit patients who prefer early appointments.

What to check before visiting: The reason for the low 2.7 rating cannot be determined from the review data alone. There may have been issues related to previous treatment processes or waiting time, so it is worth confirming by phone. Ask in advance about parking and booking procedures as well.

Practical tip: Tuesday and Wednesday have evening hours until 20:30. The clinic is only about a 4-minute walk from the station, making it the most convenient by public transport among the clinics analyzed. If you tell them at your first visit that you want only the necessary treatment, it may fit the clinic’s review pattern better.

유디중앙역치과의원 (UD Central Station Dental Clinic) - budget-friendly cavity care

Why it stands out: 21 Kakao reviews and 4 Google reviews. No rating information was provided. It has the fewest reviews among the clinics analyzed, so statistical reliability is low, but there are specific comments such as “cheap” and “no unnecessary treatment.” The reviews suggest a lower-cost model than many other clinics.

"첫 진료 예약 예약 후 이용대기 시간 30분 이내 진짜 저렴해요!! 다른 병원에서 70만원, 100만원 견적받았는데 유디에서는 48만원이네요. 선생님들 친절하셨고 과잉진료 없어서 좋았습니다! 강추~" — Suunnnnnny, 2026년 7월 4일

"사랑니 뺐아요 ㅠ 무서웠는데 진짜 빨리 빼주셔서 괜찮았어요." — 이수연1713, 2026년 6월 30일

Location: 경기 안산시 단원구 고잔1길 7 석탑프라자 7층. 707 m from Exit 1 of Central Station on Line 4 / Suin–Bundang.

Hours: Wed/Thu/Fri 09:30~18:30, Sat 09:30~14:30.

Cavity-treatment angle: Direct cavity-treatment experience is not confirmed in the reviews, but the clinic appears to have a lower treatment-cost environment than many others, which may reduce the financial burden for conservative cavity procedures such as resin or inlay treatment. However, there is not enough review data about precision or long-term outcomes.

What to check before visiting: It is closed on Mondays and Tuesdays. Because it only operates four days a week, it may be difficult to respond quickly if you have acute cavity pain. With only 21 reviews, there is not enough sample size to judge satisfaction confidently, so you should confirm the treatment plan and cost in detail during the consultation. Ask by phone about parking, the type of cavity materials used, and whether insurance applies.

Practical tip: The clinic belongs to the UD network, so you may expect a standardized service process. Since it only operates from Wednesday to Saturday, booking right after opening at 09:30 may help reduce waiting time. It can also serve as a useful price benchmark when comparing cavity estimates.

Checklist for choosing a cavity-treatment dental clinic

• Check for unnecessary treatment when diagnosing cavities — Ask whether one cavity is being split into multiple treatments or whether there is excessive pressure toward inlays or crowns.
• Get a detailed estimate before treatment — Prioritize clinics that explain costs numerically for each method, such as resin, inlay, and crown.
• Confirm insurance coverage — Check whether the clinic clearly explains which cavity-related items are covered by insurance and which are not.
• Appropriate use of X-rays — Make sure the clinic does not make the final diagnosis by visual inspection alone, but shows objective evidence through intraoral X-rays.
• Pain-management approach — If the clinic explains anesthesia and post-anesthesia pain handling in advance, it can reduce anxiety during treatment.
• Evening and weekend availability — For working adults, after-work or Saturday availability can make a major difference. Yes Plant offers evening hours until 21:00 on Tuesdays, and Yeonse Leaders until 20:30 on Mondays and Wednesdays.
• Openness to a second opinion — Clinics that remain open and non-defensive when you mention advice from another clinic tend to be more trustworthy.
• How often reviews mention “return visits” — A clinic with patterns like “I came back” or “I’ve been going there for years” is often more trustworthy than one with only one-time praise.
• Post-treatment care guidance — Check whether the clinic explains expected lifespan, care methods, and what to do if there is a problem after resin or inlay treatment.
• Prevention education — Clinics that go beyond treatment and offer oral hygiene and diet advice may lead to better long-term results.

Warning signs to watch for

• One-sided treatment recommendations and blocking other opinions — Be careful if the clinic shuts down your questions and presents one expensive procedure as the only option, saying things like “there is no way, just live like this forever.” A real review even described a case where a cavity that could have been treated with resin was pushed toward veneers.
• Rough examination style — Excessive discomfort from examination tools can be a simple mistake, but if reviews say things like “it was like hammering nails with a hammer,” you should question the precision of care and the level of patient consideration.
• Starting treatment without enough explanation — It is better to avoid clinics that begin treatment immediately without showing X-ray evidence or explaining options.
• Lack of cost transparency — A clinic that says “let’s just start” without a clear total estimate, or that adds costs midway, is not ideal. As mentioned in the UD Central Station review, clinics that state a concrete amount in advance are preferable.

Frequently asked questions

How much does cavity treatment cost in Ansan?

From the review data collected here, one amount mentioned was 480,000 KRW at 유디중앙역치과의원 (for a specific treatment before insurance). No exact pricing data was confirmed for the other clinics. Cavity treatment costs vary widely depending on the size and location of the cavity and the material used, so always compare estimates before treatment.

Is the clinic with the most reviews automatically the best choice for cavity treatment?

No. Yeonse Leaders has the most reviews at 1,872, but Ansan Ye Dental Hospital has 1,523 reviews and a rating of only 2.7. Review volume helps, but you should also consider ratings, review content, and how consistent the treatment style seems to be.

How can I find a clinic that avoids unnecessary treatment?

In the reviews analyzed, Yes Plant, Yeonse Leaders, and Ansan Ye Dental Hospital all had comments mentioning no unnecessary treatment. During the consultation, it is also a good idea to ask directly, “Do I really need to treat this cavity now?”

Which Ansan dental clinics offer cavity treatment on Saturdays or in the evening?

Yeonse Leaders offers evening hours until 20:30 on Mondays and Wednesdays, and Yes Plant offers evening hours until 21:00 on Tuesdays. Saturday appointments are available at Yeonse Leaders, Yes Plant, Ansan Ye Dental Hospital, and UD Central Station, while 안녕하세요치과의원 also operates on Sundays.

What should foreign residents check before visiting a clinic in Ansan?

Because English-speaking support varies by clinic, confirm it by phone or on the booking page before going. It is also smart to bring your ID, insurance card if applicable, and any previous dental records or X-rays so the first visit goes more smoothly.

I have a cavity and may also need orthodontic treatment. Can one clinic handle both?

Yeonse Leaders is positioned as an orthodontics clinic, so it may be able to plan cavity treatment and orthodontic care together. Since cavities often need to be addressed before orthodontic work, getting consistent care from one clinic may help coordinate your treatment schedule.

How much trust should I place in negative experiences mentioned in reviews?

In the case of 안녕하세요치과의원, one negative experience was identified among 630 reviews, but the details were specific and serious. It may have been a one-time personal experience, but if similar patterns appear in other reviews as well, it is wise to treat them as warning signs.

Conclusion

The most important standard when choosing a cavity-treatment dental clinic in Ansan is whether the clinic treats only what your teeth actually need, without unnecessary procedures. Yeonse Leaders looks like the most stable option based on a huge review base of 1,872 and consistently positive feedback, while Yes Plant stands out with an objective Kakao rating of 5.0 and strong cavity-consultation reviews. UD Central Station has a small sample but shows price competitiveness in the reviews, and Ansan Ye Dental Hospital may suit patients who value honest treatment even though its rating is low. 안녕하세요치과의원 has a major advantage in weekend availability, but because of the negative review content, it is best approached carefully and with prior awareness.
