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. You
may not feel any pain in the early stages of the infection. 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.
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. Most courses of
treatment will involve two or more visits to your dentist.
At the first appointment, the infected pulp is removed, and any abscesses can be
drained. The root canal is then cleaned and shaped ready for the filling. A temporary
filling is put in and the tooth is left to settle.
The tooth is checked at a later visit and when all the infection has cleared, the
tooth is permanently filled.
