What is a root canal treatment?

Inside the tooth is a hollow centre containing ‘pulp’. Pulp is a sensitive tissue made up of blood vessels and nerves that provides oxygen, nutrients and feeling to the tooth. The pulp is found all through the tooth and the space where the pulp sits in the root is called the root canal.

Root canal treatment is a dental procedure that replaces damaged or infected pulp in the tooth’s root canal, with a filling.
