When the nerve of the tooth is infected, a root canal may be necessary to save the tooth. A root canal is a procedure where the infected pulp is removed from inside the tooth to allow for cleaning and disinfecting before filling and sealing the tooth. This process allows you to keep your natural tooth instead of having it extracted to eliminate the infection.
