Root Canal Therapy

What is 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 tooth decay or injury.

If the pulp becomes infected, the infection may spread through the root canal system of the tooth, which can 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.

What does root canal treatment involve?
The aim of this treatment is to remove all infection from the root canal. This involves cleaning the root by removing any infected pulp. 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 a skilled and time-consuming procedure that should always be carried out by an experienced dentist. Most courses of treatment will involve two or more visits to the dental practice.

Does root canal therapy hurt?
No, a local anaesthetic is used and it should feel no different to having an ordinary filling done.

What will my tooth look like after treatment?
In the past, a root filled tooth would often darken after treatment but fortunately, this does not usually happen with modern root canal techniques. If there is any discolouration, there are several treatments including teeth whitening treatments available to restore the natural appearance.

What if a dental infection reoccurs?
Root canal treatment is usually very successful but, occasionally, the infection may return. If this happens, treatment can be repeated.

Aftercare for root canal therapy
Root-treated teeth should be cared for in just the same way as any other tooth. Remember to clean your teeth at least twice a day, preferably with a fluoride toothpaste, cut down on sugary snacks and visit your dentist for regular check-ups.

Will the tooth be safe after treatment?
Yes, however sometimes it is better to restore the tooth with a crown to provide extra support and strength to the tooth.
