Root canal therapy

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 therapy.

Why is it needed?

If the pulp becomes infected, the infection may spread through the root canal system of the tooth. This may eventually lead to an abscess. An abscess is an imflamed area in which pus collects and can cause swelling of the tissues around the tooth. The symptoms of an abscess can range from dull ache to severe pain and the tooth may be tender when you bite. 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 it should feel no different to 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.

It 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. 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. 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.

What will my tooth look like after the treatment?

In the past, a root filled tooth would often darken after treatment. However, with modern techniques this does not usually happen. If there is any discolouration, there are several treatments available to restore the natural appearance.
