Root Canals

Underneath your tooth’s outer enamel and within the dentin is an area of soft tissue called the pulp, this area contains the tooth’s nerves, veins, arteries and lymph vessels. Root canals are very small, thin divisions that branch off from the top pulp chamber down to the tip of the root. A tooth has at least one but no more than four root canals.

When the pulp becomes infected due to a deep cavity or fracture that allows bacteria to seep in, or injury due to trauma, it can die. Damaged or dead pulp causes increased blood flow and cellular activity, and pressure cannot be relieved from inside the tooth. Pain in the tooth is commonly felt when biting down, chewing on it and applying hot or cold foods and drinks.

A root canal is a procedure done to save the damaged or dead pulp in the root canal of the tooth by cleaning out the diseased pulp and reshaping the canal. The canal is filled with gutta percha, a rubberlike material, to prevent re-contamination of the tooth. The tooth is then permanently sealed with possibly a post and/or a gold or porcelain crown. This enables patients to keep the original tooth.

Root canal treatments usually involve one to three appointments.
