Root canal therapy is necessary to treat an infection that involves the internal aspect or nerve of a tooth. This can be caused by decay or if the pulp has been damaged due to fracture, injury, or multiple fillings. The internal portion of the tooth is cleaned and disinfected with a series of instruments and medicaments and a filling is placed in the internal portion of a tooth to create a complete seal. Once the canal is disinfected and the filling is placed in the tooth, the infection should resolve.
