Checklist for Choosing a Dental Clinic for Cavity Treatment
- Check specialist qualifications — Confirm through the Health Insurance Review & Assessment Service whether the clinic has a specialist in conservative dentistry or integrated dental medicine
- Confirm stage-by-stage treatment availability — Ask whether they can provide treatment from early cavities through root canal therapy
- Diagnostic equipment — Check whether they have cone beam CT or digital X-ray equipment for precise diagnosis
- Anesthesia and pain control — Ask about pain-minimizing methods such as topical anesthesia or infiltration anesthesia
- Explanation of materials and procedures — Ensure they clearly explain the pros, cons, and costs of materials such as amalgam, resin, and inlay
- Treatment plan and number of visits — They should clearly state the overall treatment plan, expected number of visits, and treatment period
- Aftercare and warranty — Check the post-treatment instructions and how issues are handled if problems arise
- Emergency response — Confirm whether you can contact them if pain or problems occur after treatment
- Cost transparency — They should disclose treatment costs in advance and explain the possibility of additional charges
Warning Signs to Watch For
It is best to avoid dental clinics that show the following signs:
Excessive treatment recommendations: Be cautious of clinics that immediately recommend crowns or implants even for minor cavities. Choose a clinic that prioritizes preserving natural teeth.
Avoiding cost explanations: Clinics that do not clearly tell you the cost before treatment, or are vague about additional charges, may cause problems later.
Immediate treatment without examination: Clinics that try to start treatment right away without enough testing and consultation may be treating you without an accurate diagnosis.
Neglecting aftercare: Avoid clinics that provide little explanation about post-treatment precautions or care, or that try to avoid responsibility if problems occur.
Frequently Asked Questions
How much does cavity treatment cost?
It depends on the severity of the cavity. Early cavity resin treatment costs around KRW 50,000-100,000, root canal treatment costs around KRW 150,000-250,000 if needed, and a crown may cost around KRW 300,000-500,000. Please confirm the exact cost through a consultation after examination.
Is anesthesia always necessary for cavity treatment?
It depends on how deep the cavity is. Shallow cavities can sometimes be treated without anesthesia, but deep cavities near the nerve require it. If you are sensitive to pain, discuss it with the doctor in advance.
What should I be careful about after cavity treatment?
On the day of treatment, avoid hard foods and be careful with hot foods until the anesthesia wears off. After resin treatment, it is best to avoid strongly colored foods such as coffee and curry for 24 hours.
Can cavities recur?
A properly treated cavity itself does not recur, but new cavities can develop around the treated area or on other teeth. Regular checkups and proper brushing can help prevent this.
Is cavity treatment possible during pregnancy?
General cavity treatment is possible during the second trimester (months 4-6). Please inform the clinic in advance of your pregnancy and discuss X-rays and anesthesia with the doctor.
I have dental anxiety. How can I overcome it?
Look for a clinic that offers sedation dentistry, such as sleep treatment or laughing gas. It is also a good idea to choose a clinic known for 'painless treatment,' such as 바로나치과의원 or 하루미치과의원.
Closing
When receiving cavity treatment in Geumjeong-gu, choose a clinic after reviewing both specialist qualifications and actual patient feedback. In particular, it is important to find a clinic that does not recommend excessive treatment and prioritizes preserving natural teeth.
This information is based on publicly available reviews and materials, and results may vary depending on an individual’s dental condition and treatment needs. For an accurate diagnosis and treatment plan, please visit the clinic in person and consult directly.
