Endodontic treatment, also called a root canal, involves removing infected, damaged or dead tissue from the tooth canal. In response to a deep cavity, an accident, a crack or even a damaged filling, a root canal prevents bacterial infection and further damage to the tooth. Moreover, it allows you to keep the affected tooth or teeth, to cure the infection and avoid an abscess.

If you experience pain or sensitivity to heat and cold, as well as swelling, see your dentist immediately to find out whether an endodontic treatment is called for.
