2D illustration detailing the fourth step of a root canal procedure, in which resin is placed within the tooth to secure the posts and fillings that have been used to fill in the tooth canals. A synthetic crown is then usually fitted over the natural tooth for added protection. 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. | |
