Root canal treatment is a procedure done to relieve pain and control any inflammation or infection that is present in the tooth. If left untreated the bacteria present inside the tooth can spread periapically and cause pathology and infection in the bone surrounding the tooth. As the bacteria enters into the pulp they cause tissue distruction spreading through the pulp and into the canal system. Thus Root canal treatment becomes necessary to remove the inflamed pulp or diseased pulp or necrotized pulp.
