2D illustration detailing the first step of a root canal procedure. After the tooth canals are cleaned, they are filled. Posts are then secured over the fillings, and a synthetic crown is usually fitted over the natural tooth for added protection. A root canal is needed when the pulp (shown here in brown) 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. | |
