Checklist for Choosing a Cavity Treatment Clinic
- Presence of a specialist in conservative dentistry — Confirm expertise in cavity treatment and root canal therapy
- Availability of cone-beam CT — Check for 3D imaging equipment for precise diagnosis
- Anesthesia method and pain control — Whether surface anesthesia plus infiltration anesthesia are used step by step
- Level of explanation about treatment — Whether the current condition and treatment plan are explained in detail
- Reservation system — Structured booking management that reduces waiting time
- Choice of materials — Explanation of both insurance-covered and non-covered material options
- Follow-up care plan — Post-treatment monitoring and additional care measures
- Emergency response — A system that allows contact if issues arise after treatment
- Hours and accessibility — Clinic hours and transportation convenience that fit your schedule
- Cost transparency — Accurate cost estimates before treatment and installment payment options
Warning Signs to Watch For
Excessive same-day treatment recommendations: Avoid clinics that want to treat multiple cavities all at once during the first visit. A proper dental clinic should explain the treatment plan thoroughly and proceed step by step after discussing it with the patient.
Diagnosis without X-rays: To accurately check the depth of cavities and whether the nerve is affected, radiographic imaging is essential. Be cautious of clinics that make treatment plans based only on visual inspection.
Only recommending non-covered materials: Clinics that recommend only non-covered materials without explaining insurance-covered options may be driven more by commercial interests. Choose a clinic that presents various options suited to the patient’s condition.
Ignoring pain complaints: If you say it hurts during treatment and they keep going by telling you to just bear with it, that is a red flag. Look for a clinic that prioritizes patient pain above all else.
Frequently Asked Questions
How much does cavity treatment cost?
With insurance, amalgam fillings cost about 10,000-20,000 KRW and resin fillings about 30,000-50,000 KRW. If root canal treatment is needed, it is around 80,000 KRW for front teeth and 150,000 KRW for molars. If a crown is needed, insurance-covered options cost about 200,000-300,000 KRW, while non-covered materials can range from 500,000 to 1,000,000 KRW.
How painful is anesthesia during cavity treatment?
Using the latest topical anesthetics can greatly reduce the sting of the needle. Many patients leave reviews saying it "hurt less than expected." If you are very afraid of anesthesia, it is a good idea to consult the clinic in advance before your visit.
Is root canal treatment always necessary?
If the cavity has reached the tooth’s nerve, root canal treatment is essential. If left untreated, it can lead to severe pain and even infection spreading to the bone. Get an accurate diagnosis with cone-beam CT and decide after discussing it with a specialist.
How long does treatment take?
Simple cavity fillings can be completed in one visit, root canal treatment usually takes 2-3 visits, and treatment involving a crown may require 4-5 visits. The exact schedule depends on the condition of the tooth, so confirm after diagnosis.
How is children’s cavity treatment different?
We recommend treatment at a clinic with a specialist in pediatric dentistry. Because primary teeth behave differently and treatment planning must consider cooperation level, choosing a clinic like 연세위드치과 with a pediatric dentistry specialist is advisable.
Can emergency treatment be done without a reservation?
If you have acute pain, most dental clinics will provide emergency first aid, but full treatment is usually done after a reservation is made. In particular, on weekends or at night, you may need to use an emergency room or an on-duty dental clinic.
