A root canal is a nonsurgical endodontic treatment that treats the inside of an infected, inflamed, irritated or damaged tooth or dental pulp. Typically, this is caused by a deep cavity, chip or cracked tooth, trauma to the face or large fillings.
Typically, the dental pulp is found in the center of the tooth that is made up of living connective cells and tissues, such as nerves and blood vessels.
With that, a root canal treatment removes the pulp inside the tooth allowing the endodontist the ability to clean, shape, fill and seal the tooth. Essentially, repairing, restoring and saving the neglected tooth.
