How much does cavity treatment cost?
The cost varies depending on the size and location of the cavity. A small cavity treated with resin costs about 50,000 to 100,000 KRW, a larger cavity treated with an inlay costs about 150,000 to 300,000 KRW, and if root canal treatment is needed, including a crown, it can cost around 500,000 to 1,000,000 KRW. Front teeth are covered by insurance, which lowers the out-of-pocket cost.
How painful is root canal treatment?
These days, anesthesia techniques are advanced, so there is almost no pain during treatment. However, after the anesthesia wears off, there may be slight discomfort for 2 to 3 days, and taking the prescribed pain reliever is usually enough to manage it.
What should I be careful about after cavity treatment?
On the day of treatment, avoid hard or sticky foods and do not chew on the treated side. For a few days, it is also best to avoid very hot or cold foods. Be especially careful if you have a temporary restoration.
How can I prevent cavities?
The basics are brushing properly three times a day, using dental floss, getting regular scaling every six months, and using fluoride toothpaste. Reduce sugary foods, brush right after meals, and get a regular dental checkup twice a year.
Is cavity treatment for children different from adults?
Children have smaller teeth and are less cooperative, so specialized pediatric dental care is needed. Baby tooth cavities can also affect permanent teeth if left untreated, so they must be treated. Laughing gas or sedation treatment can help children receive care more comfortably.
How long does treatment take?
Small cavities can be finished in one or two visits, but if root canal treatment is needed, it usually takes 3 to 5 visits, and if a crown is added, about 6 to 8 visits may be required. The interval between treatments is usually about one week, and if there are many affected areas, the total period will be longer.
