Warning Signs to Watch Out For
When choosing a clinic for tooth decay treatment, it is best to avoid places with the following signs: Excessive recommendations for additional treatment: Be cautious if they strongly push expensive extra treatments such as implants or orthodontics when you only came for simple tooth decay treatment. Skipping the diagnostic process: Clinics that try to start treatment immediately without X-rays or an oral examination may not be able to make an accurate diagnosis. Refusing to disclose costs in advance: Clinics that do not clearly explain the expected cost before treatment or say “we have to do it first to know” may lead to later billing problems. Frequent changes in medical staff: Clinics where a different doctor treats you every visit may have difficulty maintaining a consistent treatment plan and aftercare.Frequently Asked Questions
How many visits does tooth decay treatment usually take?
It depends on the size of the cavity, but it is generally completed in 1–3 visits. Small cavities can be finished the same day, while cases requiring root canal treatment may take 2–4 weeks.
How much does tooth decay treatment cost?
With insurance coverage, resin fillings cost about 30,000–50,000 KRW, and inlays cost about 100,000–150,000 KRW. If a crown is needed, the cost is usually in the 300,000–500,000 KRW range. Prices vary by clinic, so please get a consultation in advance.
Is tooth decay treatment possible without anesthesia?
Shallow cavities can sometimes be treated without anesthesia, but deep cavities close to the nerve require it. If you want painless treatment, discuss your concerns about anesthesia with the doctor.
What should I be careful about after treatment?
For 2–3 hours after treatment, avoid hard foods, and be careful not to bite your tongue or lips until the anesthesia wears off. For about a week, avoid chewing hard foods on the treated area.
When can I return to normal eating after tooth decay treatment?
For resin fillings, you can eat normally the same day. For inlays or crowns, normal eating is possible after 24 hours, once the adhesive has fully set.
How often should I get regular checkups?
In general, regular checkups every 6 months are recommended. If you frequently get cavities, checkups every 3–4 months are advisable.
