Endodontic treatment is done to remove the infected pulp, stop the infection, and preserve your teeth. Although most people use the term root canal to refer to the treatment, it is the natural cavity that houses the pulp. Our teeth have three layers: the enamel, dentine, and the pulp cavity. The pulp chamber or root canal cavity contains nerves and tissues that support the teeth during the development stage. The cavity, once it is infected it can cause pain and lead to the deterioration of the tissues and teeth. Not only that but if left unattended, the infection can spread to the surrounding tissue, hence the need for a root canal.
