What Is Root Canal?

Underneath your tooth’s outer enamel and within the dentin is an area of soft tissue called the pulp tissue. While a tooth’s pulp tissue does contain nerve fibers, it is also composed of arteries, veins, lymph vessels, and connective tissue. Each tooth’s nerve enters the tooth at the very tip of its roots. From there, the nerve runs through the center of the root in small “root canals,” which join up with the tooth’s pulp chamber. 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.
