What is a root canal?

A root canal removes infected or inflamed pulp from inside a tooth, then cleans, disinfects and seals the canals. It is done to save a natural tooth that would otherwise need to come out. Most back teeth need a crown afterward.

Root canal: specialist or general dentist?

Many general dentists perform root canals, especially on front teeth and premolars. Endodontists are root canal specialists with 2–3 extra years of training. They are often recommended for molars with curved or hidden canals, retreatments, and teeth with unusual anatomy.

2 of Costa Mesa's 42 clinics offering root canals have an endodontist on staff. See endodontists in Costa Mesa
