What Happens During a Root Canal?
Acid formed by bacteria in the mouth can cause tooth decay over time. If decay reaches far enough, a root canal may be necessary. Learn more about root canal procedures.

Bacteria in the Mouth
After eating, food particles and liquids that contain sugars and starches are left behind on the teeth. Bacteria that also exists in the mouth combines with the left-over substances and forms acids.Effects of Acids on Tooth Enamel
The acid can eventually destroy the protective enamel covering on the teeth, causing holes or cavities, called tooth decay or caries. Tooth decay can lead to infection, causing pain and inflammation.When Is a Root Canal Needed?
Beneath the enamel of the tooth is the dental pulp, soft tissue that contains nerves, blood vessels and connective tissue. Dental pulp extends from the crown of the tooth to the root. If decay from cavities reaches the dental pulp, a root canal is required.What Happens During a Root Canal?
During root canal, the tooth and area around the tooth are anesthetized. A hole is then drilled into the tooth and the pulp tissue is removed from the tooth. The canals are then cleaned and filled with medicine. A permanent seal, or crown, is put in place over the tooth.Risks of a Root Canal
There are several potential complications associated with this procedure that should be discussed with a doctor prior to surgery.Copyrighted animations provided by Blausen Medical.
