This part of inner tooth anatomy is of central concern when dentists undertake endodontic or root canal treatment.
When tooth pulp is diseased, pus can build up at the apex of the root, and if left untreated it can cause deterioration of the bone.
Root canal therapy is a very reliable treatment and the success rate is close to 95 percent. Once infected pulp is removed, bone heals and fills in within six to 12 months.
