The pulp can become irreversibly damaged
by bacteria, which gets in because of decay, very deep restorations,
fractures, trauma or periodontal disease. The bacterial infection
can spread throughout the root canal and into the jaw, where
an abscess may form. If the problem isn’t detected and
treated, it can eventually result in great discomfort.
In order to preserve a tooth in which this type of infection has
occurred, it is necessary to remove the diseased pulp tissue. The
procedure is known as non-surgical root canal
therapy.
