Root canal treatment
Root canal treatment (also called endodontics) is needed when the blood supply or nerve of the tooth (also known as the pulp) has become infected through decay or injury.
What is a root canal ?
Every tooth starts by having both blood and nerve supply. These minute structures enter at the bottom of the root, proceed up the root through the root canal and form the pulp at the crown of the tooth. They supply the live tooth with blood, internal nutrients and feeling.
Why do I need root canal treatment ?
If the pulp of your tooth becomes infected, the infection may spread and eventually lead to an abscess. An abscess is an inflamed area in which pus collects, with symptoms ranging from a dull ache to severe pain. If root canal treatment is not carried out, the infection is likely to spread and the tooth may end up having to be extracted.
