A root canal is a common dental procedure that is performed to alleviate a tooth ache or chronic infection inside your tooth.
At the center of your tooth is tissue referred to as pulp. Pulp is a collection of blood vessels that helps to build the surrounding tooth. 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.
