This procedure removes dental pulp when it has become dead or infected. Dental pulp is the soft core of the tooth. It contains nerves, blood vessels, and connective tissue. The pulp extends from the top of the tooth, called the crown, all the way down to the roots, in branches called canals.

Problems from the procedure are rare, but all procedures have some risk. Your dentist will review potential problems, like:
- Pain and swelling
- Surgical-wound infection
- Persistent abscess
- Inability to save the tooth
Factors that may increase the risk of complications include:
- Immune system disorders
- Bleeding disorders
- Circulatory problems that can cause healing problems, such as diabetes
Be sure to discuss these risks with your dentist before the procedure.
