Has your dentist or endodontist told you that you need a root canal? If so, you're not alone. Millions of teeth are treated and saved each year with root canal, or endodontic, treatment. This page explains root canal treatment in detail, how it can relieve your tooth pain and save your smile.
Root canal treatment is an often straightforward procedure to relieve dental pain and save your teeth. Patients typically need a root canal when there is inflammation or infection in the roots of a tooth. During root canal treatment, an endodontist who specializes in such treatment carefully removes the pulp inside the tooth, cleans, disinfects and shapes the root canals, and places a filling to seal the space.
“Endo” is the Greek word for “inside” and “odont” is Greek for “tooth.” Endodontic treatment treats the inside of the tooth. Root canal treatment is one type of endodontic treatment.
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.
