Root Canal Treatment

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

Why is root canal treatment needed?

If the pulp gets infected, the infection can spread through the root canal system 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 will need to be taken out.

Does it hurt?

No. As a local anaesthesia is used so it should feel no different to having an ordinary filling done.

What does it involve?

The treatment’s aim is to remove all infection from the root canal. The root is then cleaned and filled to avoid any further infection. Root canal treatment is a time-consuming and skilled procedure. Most series of treatment will involve two or more visits to your dentist. At the first visit the infected pulp is removed, and any abscesses, which can be present, may also be drained at this time. The root canal is then cleaned and shaped to ready it for the filling, then a temporary filling is placed in and the tooth is left to settle. At a later visit the tooth is checked and when all the infection has cleared, the tooth is permanently filled.

What will my tooth look like after treatment?

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

What if it happens again?

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

What if I dont have the treatment?

Another option is to have the tooth out. After the pulp is destroyed, it can’t heal and it is not recommended to leave an infected tooth in the mouth. Even though some people would prefer an extraction, it is normally best to keep as many natural teeth as possible.

Will the tooth be safe after treatment?

Yes. However, it is better to rebuild the tooth with a crown to provide extra strength and support to the tooth.

Where can this treatment be carried out?

Root canal treatment is a standard dental procedure, which your dentist will be happy to do for you.


Care for root-treated teeth should be taken just the same as any other tooth. Remember to clean your teeth, preferably with a fluoride toothpaste at least once a day. Reduce the intake of sugary snacks, and keep them only to mealtimes if possible. See your dentist for regular check-ups.
