A root canal treatment is used to repair and save a tooth that is badly decayed or becomes infected. During a root canal procedure, the nerve and pulp are removed and the inside of the tooth is cleaned and sealed. Without root canal treatment, the tissue surrounding the tooth will become infected and abscesses may form. Root canal treatment is an often straight forward procedure to relieve dental pain and save your teeth. “Root canal” is the term used to describe the natural cavity within the center of the tooth. The pulp or pulp chamber is the soft area within the root canal. The tooth’s nerve lies within the root canal. A tooth’s nerve is not vitally important to a tooth’s health and function after the tooth has emerged through the gums. Its only function is sensory — to provide the sensation of hot or cold. The presence or absence of a nerve will not affect the day-to-day functioning of the tooth. With root canal work and treatment, restoring severely damaged teeth is now possible.
