Root canal treatment

NHS Inform logo

Information for the public about root canal treatment.

The information comprises:

Root canal treatment is a dental procedure to treat infection at the centre of a tooth (the root canal system). Root canal treatment is also called endodontics. The infection is caused by bacteria that live in the mouth and invade the tooth when:

  • tooth decay occurs
  • fillings leak
  • teeth are damaged by trauma, such as a fall

See the Health A-Z topic on Tooth decay for more information about how decay starts.
