(HealthDay News) — Millions of teeth are treated by root canal each year, says the American Association of Endodontists. A root canal is the process of removing an injured or diseased tooth.
The procedure often is the best way to relieve serious pain and bring a tooth back to health.
Patients are given anesthesia for the procedure, so it typically is not painful. However, a root canal can be sore, numb or uncomfortable for a few days.
