How a Root Canal can save a Tooth

Root canal therapy works by cleaning and shaping the inside of the tooth, then refilling and sealing the root canal to prevent bacteria from creating further infection. A root canal can save a tooth by helping to prevent further decay and restoring the tooth the normal function. A crown is placed to protect the inside of the tooth, in most cases returning the tooth to normal permanently.

Almost any tooth can receive endodontic treatment. However, some teeth cannot be saved using this method. Severely fractured or unsupported teeth, and teeth with inaccessible roots sometimes cannot be saved and may require other restoration procedures instead.
