ENDODONTICS (ROOT CANALS) is a specialized procedure and treatment that requires a dental specialist. Endodontics involves the soft inner tissue of the teeth called the pulp. This procedure is common and happens if a cavity was not filled in time to prevent the decay leading to infection decay.
The only alternative to a root canal procedure is having the tooth extracted and replaced with a bridge, implant, or removable partial denture to restore chewing function and prevent adjacent teeth from shifting. These alternatives are not only more expensive than a root canal procedure but require more treatment time and additional procedures to adjacent teeth and supporting tissues.
