2D illustration showing a treated tooth after a completed root canal procedure. A root canal is needed when the pulp at the centre of a tooth, which contains the nerve and blood supply, becomes infected. The bacteria kill and replace the pulp and eventually spread into the surrounding tissue, causing inflammation. Treatment involves drilling into the tooth to remove the infected area, cleaning the interior of the tooth and then filling the hollow. A synthetic crown has been fitted over the treated tooth for added protection. | |
