Root canal treatment (also known as endodontic therapy) aims to clean, shape and fill the entire root canal of a tooth. A root canal infection can be caused by several things, including decay, injury and possibly also gum disease. Root canal treatment can repair your damaged tooth without it having to be removed.
The aim of root canal treatment is to get rid of the damaged pulp and the bacteria that are causing the infection. It involves removing inflamed or dead nerves and blood vessels from the centre of your tooth. This is done by drilling a hole through the top of your tooth to the root canal and removing the dead tissue. The empty root canal system is then cleaned, filled and a permanent seal put over the top of your tooth. The procedure may be carried out over one or two visits to your dentist and it is completely painless.
