"Endo" is the Greek word for "inside" and "odont" is Greek for "tooth".  Endodontic treatment involves 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 is a hard layer called  dentin, inside 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.


Reasons for endodontic treatment

Endodontic treatment (or root canal therapy) is performed to save the natural tooth. In spite of the many advanced restorations available, most dentists agree that there is no substitute for healthy, natural teeth.

Here are a few of the main causes of inner tooth damage:

Bacterial infections – Oral bacteria is the most common cause of endodontic problems. Bacteria invade the tooth pulp through tiny fissures in the teeth caused by tooth decay or injury. The resulting inflammation and bacterial infection jeopardize the affected tooth and may cause an abscess to form.

Fractures and chips – When a large part of the surface or crown of the tooth has become completely detached, root canal therapy may be required. The removal of the crown portion leaves the pulp exposed, which can be debilitating, painful and problematic.

Injuries – Injuries to the teeth can be caused by a direct or indirect blow to the mouth area.  Some injuries cause a tooth to become luxated or dislodged from its socket. Root canal therapy is often needed after the endodontist has successfully stabilized the injured tooth.

Avulsion – If a tooth has been knocked out of the socket, it is important to rinse it and place it back into the socket as quickly as possible. If this is impossible, place the tooth in special dental solution (available at pharmacies) or in milk. These steps will keep the inner mechanisms of the tooth moist and alive while emergency dental treatment is sought. The tooth will be affixed in its socket using a special splint, and the endodontist will then perform root canal therapy to save the tooth.

Large or Deep Fillings - The larger the filling or the deeper it is, relative to the pulp, will increase the chance that root canal therapy will be necessary.

Repeated Dental Procedures - Each time a procedure is done to a tooth, no matter how long ago it was done, will increase the chance that root canal therapy will be necessary.
