What is a Root Canal?

A root canal is a treatment used to repair and save a tooth that is badly decayed or becomes infected. During a root canal procedure, the nerve and pulp are removed and the inside of the tooth is cleaned and sealed. Without treatment, the tissue surrounding the tooth will become infected and abscesses may form.

"Root canal" is the term used to describe the natural cavity within the center of the tooth. The pulp or pulp chamber is the soft area within the root canal. The tooth's nerve lies within the root canal.

The Importance of Early Dental Visits

At the sight of my son's first tooth, it dawned on me: I had been so focused on every other detail of his development that I knew almost nothing about dental care for little choppers. According to Clarice Law, DMD, MS, assistant professor in the Pediatric Dentistry and Orthodontics sections at the UCLA School of Dentistry, it pays to start dental visits early. "I like to see kids by age 1," Law says. Mostly, first visits are about getting kids used to the dentist's chair and educating parents about...

A tooth's nerve is not vitally important to a tooth's health and function after the tooth has emerged through the gums. Its only function is sensory -- to provide the sensation of hot or cold. The presence or absence of a nerve will not affect the day-to-day functioning of the tooth. 

Why Does Tooth Pulp Need to Be Removed?

When a tooth's nerve tissue or pulp is damaged, it breaks down and bacteria begin to multiply within the pulp chamber. The bacteria and other decayed debris can cause an infection or abscessed tooth. An abscess is a pus-filled pocket that forms at the end of the roots of the tooth. An abscess occurs when the infection spreads all the way past the ends of the roots of the tooth. In addition to an abscess, an infection in the root canal of a tooth can cause:

  • Swelling that may spread to other areas of the face, neck, or head
  • Bone loss around the tip of the root
  • Drainage problems extending outward from the root. A hole can occur through the side of the tooth with drainage into the gums or through the cheek with drainage into the skin.

What Damages a Tooth's Nerve and Pulp in the First Place?

A tooth's nerve and pulp can become irritated, inflamed, and infected due to deep decay, repeated dental procedures on a tooth, and/or large fillings, a crack or chip in the tooth, or trauma to the face.

Only 18.5% of Americans never floss. You are missing out on a simple way to make a big difference in the health of your mouth. Regardless of how well you brush, plaque still forms between your teeth and along your gums. Floss removes food trapped between the teeth and removes the film of bacteria that forms there before it turns to plaque, which can cause inflamed gums (gingivitis), cavities, and tooth loss. Try flossing just one tooth to get started.

You are one of 31% of Americans who don't floss daily. You are missing out on a simple way to make a big difference in the health of your mouth. Regardless of how well you brush, plaque still forms between your teeth and along your gums. Toothbrush bristles alone cannot clean effectively between these tight spaces. Flossing removes up to 80% of the film that hardens to plaque, which can cause inflamed gums (gingivitis), cavities, and tooth loss. Aim for 3 more days!
