, knows that when a cavity has gone to the pulp of a tooth, that it causes an infection of the nerve. Infections in the nerve or severe trauma that has happened to the tooth need to be solved with a root canal. Regular checkups help to avoid the need for a root canal. The pulp cannot heal on its own so once it is infected, a root canal must be done. Some signs that it has been infected are: sensitivity to hot/cold, pain, swelling, or a bad taste in the mouth.
