Endodontics is that
branch of dentistry which deals with the dental pulp and the tissues
surrounding the tooth. Generally speaking when the dental pulp is
damaged or diseased, root canal treatment is the inevitable progression
in order to preserve the tooth.
Your dentist may wish to refer
you to an endodontist (a dentist who specialises
in root canal treatment)
for a second opinion or to actually undertake this
treatment for you. This step is indicated when the
diagnosis is complicated or when treatment is
difficult.
