A root canal is performed when the inside of the tooth, known as the pulp, becomes infected or inflamed. The root canal procedure cleans out and disinfects the space, which is then filled with a rubber-like material. A filling or crown closes the space, and the tooth can function as normal.
How can infection occur?
The pulp, soft tissue in the centre of the tooth, may become infected due to deep decay, trauma to the tooth, chips, cracks or due to multiple procedures done on the tooth.
