Root canal treatment or endodontic treatment is a very common dental procedure to eliminate inflammation or infections deep inside the tooth. This treatment can save your natural teeth and prevent more costly tooth replacement procedures. In the center of your tooth is the root canal space, which contains the pulp tissue. The pulp is the collection of nerves and blood vessels within the tooth that stimulates tooth development when we are young. As we get older, the pulp serves only a sensory purpose. Infection of the pulp can be caused by trauma to the tooth, deep decay, cracks and chips, or repeated dental procedures. Symptoms of the infection can be identified as visible injury or swelling of the tooth, sensitivity to temperature, or pain in the tooth and gums.
