Root Canal Treatment
To treat the infection in the root canal
Root canal treatment (endodontics) is needed when the blood or nerve supply of the tooth (the pulp) is infected through decay, trauma, gum disease, etc. You may not feel any pain in the early stages of the infection or it can be very painful at first and then subside. In some cases your tooth could darken in colour, which may mean that the nerve of the tooth has died (or is dying). This would need root canal treatment.
