Root canal treatment (also called endodontics) is needed when the blood or nerve supply of the tooth (known as the pulp) is infected through decay or injury.

If the pulp becomes infected, the infection may spread through the root canal systems of the tooth, which may eventually lead to an abscess.
If root canal treatment (RCT) is not carried out, the infection will spread and the tooth may need to be taken out.

Does it hurt?
No. A local anaesthetic is used and the whole procedure should feel no different to that of having an ordinary filling done.

What does it involve?
The aim of the treatment is to remove all infection from the root canal. The root is then cleaned and filled to prevent any further infection.
Root canal treatment is a skilled and time consuming procedure.
At the first appointment, the infected pulp is removed. Any abscesses, which may be present, can also be drained at this time.
The root canal is then cleaned and shaped ready for the filling.
