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 decay or injury.
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 (RCT) is not carried out, the infection will spread and the tooth may need to be taken out.
Does it hurt?
No. A local anaesthesia is used and it should feel no different to having an ordinary filling done.
What does it involve?
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 one or two visits, although in certain circumstances more visits may be necessary. For back teeth, we normally advise placing a crown to improve the seal & help secure a tooth weakened by the root treatment, preventing it from breaking or splitting.
What will my tooth look like after treatment?
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 available to restore the natural appearance.
What if it happens again?
Root canal treatment is usually very successful. However, if the infection comes back the treatment can be repeated. In case of repeated infection, the tooth may need to be removed.
What if I don’t have the treatment?
If the tooth is left, you may get swelling, pain or infection, with extraction usually indicated if the tooth becomes unsavable. 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, at Lightwood we believe it is usually best to keep as many natural teeth as possible.
Where can this treatment be carried out?
Root canal treatment is a routine dental procedure, which your dentist will be happy to do for you. However, on occasion we may need to refer you to a dentist who has extra qualifications and training in providing root treatments, especially if the treatment is particularly difficult or complex. We are delighted to offer this service in-house, with specialised equipment including microscope available for our visiting dentist, Neia, to provide treatment for more challenging teeth. We also accept referrals into Lightwood via our online referral form.
What about aftercare?
Root-treated teeth are weaker than healthy teeth, which is why your dentist will normally recommend a crown after treatment to strengthen and support the residual tooth. Avoid anything too hard or chewy on the root treated tooth. Otherwise, care for the tooth like you would an ordinary healthy tooth. Remember to clean your teeth twice a day, using a fluoride toothpaste, with interdental cleaning at least once daily. Cut down on sugary snacks, and keep them only to mealtimes if possible. See your dentist for regular check-ups.
