When pulp is damaged, it breaks down, and bacteria begin to multiply within the pulp chamber. The bacteria and other dying pulp remnants can cause an infection or abscessed tooth. An abscess is a pus-filled pocket that forms at the end of a toothâs root. In addition to an abscess, an infection in the root canal of a tooth can cause:
A root canal removes the diseased or infected part of the tooth, and it removes the nerve from a severely broken tooth, allowing the tooth to be saved. You may need a root canal if you have a severe toothache, usually along with swelling in your jaw around your tooth. When the pulp (the soft tissue inside the roots and center of a tooth) is damaged from a cracked tooth or other injury, or from a deep cavity, it can get infected.
