1. ROOT CANAL TREATMENT / ENDODONTIC TREATMENT Tooth structure At the center of a tooth is a hollow area that houses soft tissue, known as pulp . This hollow area contains a relatively wide space towards the chewing surface of the tooth called the pulp chamber. This pulp chamber is connected to the tip of the root of the tooth via thin hollow pipe-like canals—hence, the term "root canal". Human teeth normally have one to four canals; teeth toward the back have the most canals. These canals run through the centre of the roots like pencil lead runs through the length of a pencil. The tooth receives nutrition through the blood vessels and nerves traversing these canals. Occasionally, a cavity on the outside of the tooth may allow this soft tissue to become infected. If left untreated a serious jaw infection can result. The infection and inflammation is very painful in most cases. Treatment should take place before this happens.
