Root canal treatment

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. The pulp needs to be carefully removed and the area within the tooth sealed to prevent new infection.

Dr Marina Spanaki is our dentist with special interest in endodontics. She uses a microscope to carry out this treatment to the highest possible standards.

Why is root canal treatment 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. If root canal treatment is not carried out, the infection will spread, and the tooth may need to be taken out.

What does it involve?

The aim of the treatment is to remove all infection from the root canal without discomfort to you. 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. 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. It is best to restore the tooth with a crown to provide extra protection and strength to the tooth.

Root canal treatment is usually very successful. However, if the infection comes back the treatment can be repeated.

Are there other options?

The alternative is to have the tooth out. 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.
