Root Canal Therapy
What is root canal therapy, or endodontic treatment?

"Endo" is the Greek word for "inside" and "odont" is Greek for "tooth." Endodontic treatment (root canal therapy) treats the inside of the tooth.

To understand root canal therapy, 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.



What are the signs of needing root canal therapy?

Signs to look for include pain, prolonged sensitivity to heat or cold, tenderness to touch and chewing, discoloration of the tooth, and swelling, drainage and tenderness in the lymph nodes as well as nearby bone and gums. Sometimes, however, there are no symptoms.

How does root canal therapy save the tooth?

Dr. Freed removes the inflamed or infected pulp, carefully cleans and shapes the inside of the canal, a channel inside the root, then fills and seals the space. Afterwards, if you have gone to a specialist for root canal therapy, you will return to your dentist, who will place a crown or other restoration on the tooth to protect and restore it to full function. After restoration, the tooth continues to function like any other tooth.
