“Endo” is the Greek work for “inside” and “odont” is Greek for “tooth.” Endodontic treatment is, therefore, a dental procedure that treats the inside of the tooth.
Understanding the anatomy of the tooth will help to clarify how endodontic treatment works. Inside the tooth, under both the white enamel and the hard layer called the dentin, is a soft tissue called the pulp. The pulp contains blood vessels, nerves and connective tissue.
The pulp extends from the crown of the tooth to the tip of the roots where it connects to tissues surrounding the root. The pulp is important during a tooth’s growth and development. However, once a tooth is fully mature, it can actually survive without the pulp.
