(HealthDay News) -- A root canal is needed when the tissue inside a tooth becomes infected or inflamed. During the procedure, the dentist removes the infected tissue and seals the tooth, protecting it from further infection.
Here's what to expect after the procedure, courtesy of the American Dental Association:
- The tooth probably will be sensitive, sore or painful for a few days. You can take an over-the-counter pain medication for relief.
- Avoid chewing or biting with the damaged tooth until it has been fully restored, usually with a dental crown.
- If you have severe pain or pressure in the tooth, or pain that lasts more than a few days, call your dentist.
