Root canal treatment is necessary when the pulp (soft tissue inside your teeth containing blood vessels, nerves and connective tissue) becomes inflamed or diseased. During root canal treatment, your dentist or endodontist (a dentist who specializes in treating the insides of teeth) removes the diseased pulp. The pulp chamber and root canal(s) of the tooth are then cleaned and sealed. If the infected pulp is not removed, pain and swelling can result, and your tooth may have to be removed.

Root canal treatment removes the diseased pulp along with the tooth’s nerve (located within a tooth’s root canal).
Causes of an infected pulp could include:
- A deep cavity
- Repeated dental procedures
- A cracked or broken tooth
- Injury to the tooth (even if there’s not a visible crack or chip)
