An endodontist is a dentist who specializes in the diagnosis and treatment of diseases of the dental pulp and the tissues surrounding the root of a tooth. Endodontists are experts in performing root canals, which are procedures that remove infected or damaged tissue from the inside of a tooth. Root canals are often necessary to save a tooth that would otherwise need to be extracted.
Endodontists play an important role in maintaining oral health. They help to prevent the spread of infection, relieve pain, and save teeth that would otherwise be lost. Endodontic treatment can also help to improve a patient's overall health by eliminating the source of infection in the mouth.
