Endodontic treatment, also known as root canal treatment, is considered the only treatment method when the tooth pulp (tooth nerve) is attacked by microorganisms, creating an irreversible inflammation. Many people associate this situation with pain, unpleasant sensations, and often with tooth loss. Endodontic treatment involves the thorough removal of the infected or irreversibly inflamed pulp and then tightly filling the cleaned canals with an appropriate material.
