Root canal treatment is needed when the blood or nerve supply of the tooth (known as the pulp) is infected through decay or injury as the infection may spread through the root canal system of the tooth.  This 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.

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.

The tooth is checked at a later visit and when all the infection has cleared, the tooth is permanently filled and restored with a crown to provide extra support and length to the tooth.

Once the pulp is destroyed, it can’t heal and it is not recommended to leave an infected tooth in the mouth. Although some people would prefer an extraction, it is usually best to keep as many natural teeth as possible.

Root-treated teeth should be treated just the same as any other tooth. Remember to clean your teeth at least once a day, preferably with a fluoride toothpaste. Cut down on sugary snacks, and keep them only to mealtimes if possible.
