Endo is the Greek word for “inside” and odontis Greek for “tooth”. Endodontic treatment covers the inside of the tooth. To understand endodontic treatment, it helps to know something about the anatomy of the tooth. Inside the tooth, under the white enamel and a hard layer called the dentin, is a soft tissue called the pulp. The pulp contains blood vessels, nerves, and connective tissue and creates the surrounding hard tissues of the tooth during development. The pulp extends from the crown of the tooth to the tip of the roots where it connects to the tissues surrounding the root.

The pulp is important during a tooth’s growth and development. However, once a tooth is fully mature, it can survive without the pulp, because the tooth continues to be nourished by the tissues surrounding it. Endodontists specializes in procedures that work with the pulp and root of the tooth, especially, root canals.

Most teeth can be treated and saved. Occasionally, a tooth can’t be saved because the root canals are not accessible, the root is severely fractured, the tooth doesn’t have adequate bone support, or the tooth cannot be restored. However, advances in endodontics are making it possible to save teeth that even a few years ago would have been lost. When endodontic treatment is not effective, endodontic surgery may be able to save the tooth. Your dentist will discuss this with you.
