3층 5층 원장님 두분 다 인품 실력 훌륭하시고 저희는 거리가 있지만 바른명으로 가족 모두 진료받아요. 계시는 선생님들 다 꼼꼼하시고 친절하세요. (리베2, 2026년 7월 27일)
아이 교정하느라 다니고 있어요! 교정치과 선택하느라 많이 찾아보고 고민하고 선택한 곳입니다. 일단 세종에서 오래된 치과이며 원장님 경력이 많으시고 진단도 명확, 꼼꼼하셔서 만족하며 다니고 있습니다. 저는 최신식 장비 내세우며 많은 정보로 홍보하는 곳은 선호하지 않기 때문에 오히려 이 곳이 참 좋습니다. 아이가 겁이 많아 치료 받을 때 고생해주시는 선생님들께 죄송하고 감사합니다. 앞으로 오래오래 세종에 계셨으면 좋겠습니다. (carolline026, 2026년 4월 23일)
다시 생각해도 불쾌해서 리뷰 써요. 5층 카운터에 계시는 아주머니 응대가 정말 불쾌했습니다. 계좌이체로 정상 결제했는데도, 제가 ‘확인’ 버튼을 누른 것을 이체취소를 누른 것 아니냐며 사실 확인도 되기 전에 째려보면서 의심부터하는 응대를 하시고 마지막까지 사과 한마디 없어서 정말 불쾌했습니다. 옛날분이라 모르시는 건진 모르겠지만 이체 후 취소 불가합니다. 다른 분께는 그러지마시길 바랍니다. 기본적인 응대 태도 개선이 필요해보이네요. 표정을 눌러 반응을 남겨 보세요! (잉어윤, 2026년 4월 7일)
Location No address value was provided, so the location is not listed.
Hours Based on the provided data, hours are Monday, Tuesday, and Wednesday 09:30-19:00, and Saturday 09:00-14:00. Thursday and Friday hours were not provided.
What to check before visiting Confirm parking availability, booking method, and whether Thursday and Friday appointments are available by phone. Since 1 of the 4 reviews mentioned dissatisfaction with front-desk service, it’s a good idea to confirm reception and payment procedures before a first visit.
Practical tip Because specialist information in orthodontics and conservative dentistry is publicly available together, this clinic may be convenient if you want to discuss cavity treatment and orthodontic consultation in one place. However, the review count is small, so it’s hard to find many recent cavity-treatment experiences.
Cavity-treatment focus HIRA public information includes 1 specialist in conservative dentistry. Conservative dentistry is the department that mainly handles cavity treatment and root canal treatment. The listing of 2 cone-beam CT units suggests equipment is available for checking cavity depth and proximity to the nerve.

Hours Based on the provided data, hours are Monday through Friday 09:30-18:30, and Saturday 09:30-13:00.
What to check before visiting Because HIRA specialist information was not disclosed, check directly whether conservative dentistry is available, how root canal treatment is handled, and how X-rays are interpreted before starting cavity treatment.

Practical tip Although the Kakao rating was 2.7, individual reviews mention friendly service and careful care without overtreatment. Don’t rely on the rating alone; read the original dated reviews about cavity-related visits.

며칠을 욱신거려서 도저히 안 되겠다 싶어 신경치료 받으러 갔어요. 통증 때문에 예민해진 상태로 갔는데 원장님이 워낙 실력이 좋으셔서 손대는 순간부터 안심이 되더라고요. 신경 건드리면 아플까 봐 잔뜩 긴장했는데 어디를 어떻게 만지시는지 하나도 안 아프게 끝내주셔서 놀랐어요. 확실히 이런 건 잘하는 곳에서 받아야겠구나 싶었네요. 아프던 것도 싹 가라앉아서 살 것 같아요. (seni****, 2026년 7월 5일)
점심시간을 이용해 신경치료를 받으러 다녀왔습니다. 신경치료라 부담이 컸는데, 원장님 실력이 정말 좋으셔서 걱정이 무색할 만큼 깔끔하게 마무리됐습니다. 예민한 부위인데도 통증 없이 정확하게 치료해주시는 걸 보면서 확실히 경험이 많으신 분이라는 느낌을 받았습니다. 치료가 끝난 뒤에도 관리가 성의 있어 신뢰가 갔습니다. 결과가 만족스러워 다음에도 이곳을 다시 찾을 생각입니다. (sun6****, 2026년 7월 5일)
이가 아파서 방문했고 예약없이 갔기에 어느정도 대기시간은 예상을 했었고 엑스레이다ct다 잔뜩찍고는 의사선생님 진료보는데 정확한원인을 모르겠다 안에를 봐야할꺼같다라는 말과함께 프론트에계신 여자선생님과 상담실.금액적힌 종이에 어쩌고저쩌고 금액설명만하시길래 너무아픈데 오늘 치료는 안하는거냐하니 치료가한시간이상걸리는거라 오늘안되고 다음주에 할수있다고 하는데 진짜 어이가없네요ㅡ아파서갔는데 어느정도는 치료를 해줘야하는게 맞는거 아닌가요?오전10시경갔는데 오후에도 치료가안된다고하면ㅡㅡ접수할때 적어도치료못할수있다고 공지라도해줬어야죠.환자가얼마나많은지 모르겠지만 동네라 리뷰찾아보고 갔는데 저한테 진짜최악이네요!

Practical tip With 473 Naver reviews, there is a lot of information available, which makes it easier to find reviews by purpose such as cavities, root canal treatment, and orthodontics. In particular, the root canal reviews from 2026-07-05 repeatedly mention that treatment ended without pain.

Hours Based on the provided data, hours are Thursday and Friday 09:30-18:30, and Saturday 09:30-14:30. Monday, Tuesday, and Wednesday hours were not provided.
What to check before visiting Since HIRA specialist information is not disclosed, confirm directly whether conservative dentistry is available and whether root canal treatment can be handled before starting cavity treatment. You should also confirm Monday, Tuesday, and Wednesday hours, parking availability, and booking methods by phone.
Practical tip With only 3 total reviews, it is difficult to find enough recent cavity-treatment experiences. The realistic approach is to read all 3 reviews together with the 3.5 Google rating.
Cavity-treatment focus No cavity-treatment-specific information could be confirmed from the data because HIRA information was not provided. In the first consultation, ask specifically about cavity depth, whether root canal treatment is needed, and whether a crown is necessary.

Cavity-Treatment Clinic Selection Checklist
- Check whether HIRA specialist and treatment-category information is public — Confirm whether conservative dentistry or specialist information is listed.
- Search for cavity-treatment reviews — Look for real reviews using keywords like root canal treatment, resin, crown, and pain control.
- Ask about cone-beam CT availability — Confirm before the consultation whether the clinic has equipment to check cavity depth and nerve proximity.
- Check whether same-day treatment is possible — If you walk in without an appointment, confirm by phone whether treatment can be done the same day.
- Match ratings with individual reviews — Don’t rely only on the rating; read recent review text as well.
- Ask how treatment costs are explained — Confirm whether the clinic explains fees before treatment and possible additional costs during treatment.
- Check booking and parking convenience — Confirm parking, booking method, and waiting time by phone.
- Ask about child and family treatment — If a child needs cavity treatment, check for pediatric dentistry or family-use reviews.
- Ask about anesthesia and pain control — Ask in consultation how anesthesia is handled, what pain to expect, and how each treatment step is explained.
- Conservative-treatment approach — Confirm whether the clinic explains how it aims to preserve as much of the tooth as possible when root canal treatment or a crown is needed.
Warning Signs to Watch For
- Clinics without public HIRA information — If specialist numbers and treatment categories cannot be checked, ask directly before cavity treatment.
- Cases where same-day treatment is not explained in advance — A 2026-08-07 review for Yonsei Christmas Dental Clinic complained that same-day treatment was not available after a walk-in visit without an appointment.
- Places where ratings and review tone don’t match — UDI Dental Clinic Sejong Branch had a Kakao rating of 2.7, but recent individual reviews included positive comments. Don’t judge by rating alone.
- Clinics with too few reviews — Barunmyeong Dental Clinic has only 4 total reviews, and Yonsei Severance Dental Clinic has only 3, so there is limited basis for judgment.
