Root canal treatment, also called root canal therapy is the removal of damaged or infected nerves and tissue from the inside of your tooth.

Inside the root of every tooth is a nerve, with pulp surrounding and protecting the nerve and a blood supply that extends out the end of the root to your circulatory system. This space inside the root is called the canal space.

Root canal therapy involves drilling a small opening in the tooth, removing the nerve, blood supply and pulp. The canal is then cleaned, shaped, sterilized and the end of the root and canal space is then sealed off with a filling material, much like a cavity or hole in your tooth would be filled. A root canal is a repair to the inside of the tooth and is the only alternative for internal tooth nerve damage or tooth abscess besides having the tooth removed.

Root canal treatment allows you to keep a tooth you would otherwise have to have pulled. When there is infection inside the tooth, there is no cure. The bacteria continue to spread to the nerve and surrounding tissue.

Many people wonder why medications, like antibiodics, cannot cure the infection. The fact is that the tissues swell, cutting off the blood supply so there is no way to get the medication to the area. Yes, they can help surrounding tissue, but cannot reach the inside of the tooth.

Root canal treatment is one of life's most dreaded procedures. Although most root canals done today are pain free, their bad reputation has not been forgotten.
