Endodontic Therapy

Endodontic's, from the Greek endo (inside) and odons (tooth), is one of the 9 specialties of dentistry recognized by the American Dental Association, and deals with the tooth pulp and the tissues surrounding the root of a tooth. When the pulp (containing nerves, arterials and venules as well as lymphatic tissue and fibrous tissue) has become diseased or injured, endodontic treatment is required to save the tooth.

A root canal is the space within the root of a tooth. It is part of a naturally occurring space within the tooth that consists of the pulp chamber (within the coronal part of the tooth), the main canal(s), and more intricate anatomical branches that may connect the root canals to each other or to the surface of the root.

The smaller branches, referred to as accessory canals, are most frequently found near the route end (apex) but it may be encountered anywhere along the route length. There may be one or 2 main canals within each route. Some teeth have more variable internal anatomy than others. This space is filled with a highly vascularized, loose connective tissue, the pulp.

The dental pulp is the tissue of which the dentin portion of the tooth is composed. The formation of secondary teeth (adult teeth) is completed by 1–2 years after eruption into the mouth. Once the tooth has reached its final size and shape, the dental pulp's original function ceases for all practical purposes. It takes on a secondary role as a sensory organ.

Root canal is also a colloquial term for a dental operation, endodontic therapy, wherein the pulp is cleaned out, the spaces disinfected and then filled.

At the center of every tooth is a hollow area that houses soft tissues, such as the nerve, blood vessels, and connective tissue. This hollow area contains a relatively wide space in the coronal portion of the tooth call the pulp chamber. This chamber is connected to the tip of the root via narrow canals; hence, the term "root canal". Human teeth normally have one to four canals, with teeth toward the back of the mouth having more. These canals run through the center of the roots like pencil lead through the length of a pencil. The pulp receives nutrition through the blood vessels and nerves carry signals back to the brain to warn of adverse events and circumstances.

For a person who feels tooth pain or discomfort, a root canal may be indicated, any qualified dentist or more preferably an endodontist dust (root canal therapy specialist) should be consulted in a timely manner.
