What Is Root Canal Therapy?
Root canal therapy is a restorative dental procedure used to eliminate bacteria from the infected root canal, prevent reinfection of the tooth, and save the natural tooth. When understanding how a root canal works, you must first understand what makes up the tooth.
Your teeth have three layers:
- The outer enamel layer that covers the visible part of the tooth.
- Under the enamel is another hard layer called dentin.
- Inside the dentin is the pulp where all the blood vessels, nerves, and connective tissue are found.
The root canal is the layer that contains the pulp. When cavities or cracks damage the enamel of the teeth, bacteria can enter the pulp and cause infection. It’s important to remove the source of the problem to save your natural tooth before it has to be extracted.
