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.
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 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.
Common signs include persistent toothache, sensitivity to hot or cold, swelling, or a pimple-like bump on the gum. Your dentist will assess the tooth and may recommend root canal treatment if the pulp is infected or inflamed.
Not at all. Root canal treatment is done under local anaesthetic, so it feels similar to having a regular filling. Most patients are surprised by how comfortable the procedure is.
Once the infection has been cleared and the canal sealed, the tooth is permanently restored—often with a crown. With good care, a tooth that’s had root canal treatment can last just as long as your other natural teeth.
Includes a comprehensive dental exam, X-rays, and a routine hygiene clean performed by the dentist. A great way to get started on your journey to a healthier smile.
