The aim of this procedure is to save a tooth that has become severely infected deep inside the tooth. To treat this, the dentist will remove bacteria and dying or dead tissue from inside the tooth. Modern endodontic treatment is very similar to a routine filling and can be completed within one or two appointments. You’ll be back to smiling, chewing and biting with ease in no time.
Root canal treatment is needed when the nerve (pulp) of the tooth becomes infected. This happens through decay or injury. You may not feel any pain in the early stages of the infection or it may throb and become swollen.
If the nerve 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 inflamed area in which pus collects and can cause swelling of the tissues around the tooth. The symptoms of an abscess can range from a dull ache to severe pain, and the tooth may be tender when you bite. If root canal treatment is not done, the infection will spread and the tooth may need to be taken out.
No. Usually, a local anaesthetic is used and it should feel no different to having an ordinary filling done. There may be some tenderness afterwards but this should gradually get less over time.
The aim of the treatment is to remove all the 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.
At the first appointment, the infected pulp is removed and any abscesses can be drained. 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.
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 that will restore the natural appearance.
Root canal treatment is usually very successful. However, if the infection comes back, the treatment can sometimes be repeated. Unfortunately, there is no guarantee of saving the tooth with root canal treatment.
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 to have the tooth out, it is usually best to keep as many natural teeth as possible.
Yes. However, because a ‘dead’ tooth is more brittle, you may need to have a crown to provide extra support and strength to the tooth.
Root-treated teeth should be looked after just the same as any other tooth. Remember to clean your teeth last thing at night and at least one other time during the day, with a fluoride toothpaste. Cut down on sugary foods and drinks, and have them only at mealtimes if possible. See your dental team as often as they recommend for regular check-ups.
