Root canal therapy or endodontics is required usually when a tooth is infected or inflamed. The inflamation can result from disruption in the vessels leading to poor blood and mineral supply, periodontal disease or bacterial profileration in the area or severe trauma or fracture. The pulp can be damaged or compromised for these reasons which are why treatment is required as soon as possible.
Root Canal treatment or Endodontic therapy is a sequence of treatments for the pulp of a tooth where the end result is the elimination of infection and protection of the decontaminated tooth from future microbial invasion. Although this set of procedures is commonly referred to as a root canal, this term is imprecise.
