Checklist for Choosing a Dental Clinic for Cavity Treatment
- Specialist availability — Check whether a specialist in conservative dentistry or integrated dentistry is on site
- Diagnostic equipment — Check whether cone-beam CT is available for precise cavity diagnosis
- Treatment philosophy — Confirm whether the clinic prioritizes conservative treatment that preserves natural teeth
- Anesthesia method — Check whether two-step anesthesia or surface anesthesia is used to minimize pain
- Aftercare — Check whether they provide proper brushing instruction or a regular checkup system
- Hours — Confirm whether they offer evening or Saturday hours that fit your schedule
- Transportation access — Consider convenience such as distance from the subway station or parking availability
- Review quality — Review specific and recent feedback rather than relying only on ratings
- Reservation system — Check how easy it is to book and whether waiting time is minimized
- Transparency of treatment cost — Look for detailed cost explanations before treatment and policies that prevent overtreatment
Warning Signs to Watch Out For
It is better to avoid dental clinics that show the following characteristics:
- Excessive treatment recommendations: Immediately suggesting expensive, extensive treatment at the first visit
- Unclear costs: Failing to clearly explain treatment costs or repeatedly adding extra charges
- Hasty extraction recommendations: Recommending extraction or implants only without sufficiently considering conservative treatment options
- Inconsistent reviews: Recent reviews suddenly getting worse or only vague reviews being posted
Frequently Asked Questions
How much does cavity treatment cost?
The cost varies greatly depending on the severity of the cavity. Early cavities can be treated with resin for around 50,000 to 100,000 KRW, while extensive damage may require a crown costing around 300,000 to 800,000 KRW. If root canal treatment is needed, an additional 100,000 to 200,000 KRW may be required. Please confirm the exact cost during an in-person consultation.
How painful is cavity treatment?
Modern dentistry uses various anesthesia techniques to minimize pain. With two-step anesthesia, where a topical anesthetic is applied before the injection, or with laser treatment, most patients can receive treatment with little to no pain. The clinics introduced above all have many reviews saying they pay close attention to painless treatment.
What should I be careful about after cavity treatment?
After resin treatment, avoid hard foods for 24 hours. After crown treatment, be careful with sticky foods while wearing the temporary tooth. If you had root canal treatment, avoid chewing on that tooth until treatment is completed.
How often should I get checkups for cavity prevention?
In general, it is recommended to have a regular checkup and scaling every 6 months. If you frequently get cavities or have gum disease, visiting every 3 to 4 months is recommended.
Which specialist is best for cavity treatment?
A specialist in conservative dentistry is the expert in cavity treatment, but a specialist in integrated dentistry can also provide comprehensive care from cavities to prosthetics. Extensive damage may require help from a specialist in prosthodontics.
Which is better: saving the natural tooth or getting an implant?
If possible, it is better to save the natural tooth. Natural teeth provide excellent chewing sensation and function and also help maintain the health of the surrounding bone and gums. However, if the tooth damage is too severe to preserve, consider extraction followed by an implant only in that case.
If you are looking for a dental clinic for cavity treatment in Gangseo-gu, please choose one of the five clinics above based on your location and schedule. In particular, if you value preserving natural teeth, we recommend The Wise Dental Hospital or Jayun Chia Saligi Gangseo Moa Dental Clinic. If accessibility is your top priority, Seoul Hian Dental Clinic is a good choice.
This information is based on publicly available data analyzed as of April 1, 2026. Please be sure to confirm directly with the dental clinic before receiving treatment. The appropriate treatment method may vary depending on your oral condition, so make your decision after 충분한 consultation with a specialist.
