Root Canal Treatment

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.

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.

What Are the Signs That a Root Canal Is Needed?

Sometimes no symptoms are present; however, signs you may need a root canal include:

• Severe toothache pain upon chewing or application of pressure
• Prolonged sensitivity/pain to heat or cold temperatures (after the hot or cold has been removed)
• Discoloration (a darkening) of the tooth
• Swelling and tenderness in the nearby gums
• A persistent or recurring pimple on the gums

The final step may involve restoration of the tooth. Because a tooth that needs a root canal often is one that has a large filling or extensive decay or other weakness, a crown, crown and post, or other restoration often needs to be placed on the tooth to protect it, prevent it from breaking, and restore it to full function.
