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:

  1. The outer enamel layer that covers the visible part of the tooth.
  2. Under the enamel is another hard layer called dentin.
  3. 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.

Signs You May Need a Root Canal

You may need a root canal if you’ve experienced any of the following:

  • Lack of room in the jawbone has caused overcrowding of the teeth
  • Difficulty chewing
  • Sensitivity to hot and cold temperatures
  • Trauma has rendered the tooth unsalvageable
  • Advanced periodontal (gum) disease has damaged the connective tissues and bone surrounding the teeth
  • Discoloration or darkening of the tooth
  • Severe tooth pain

If you’re experiencing any of these symptoms, contact our Sudbury office at (978) 443-3111 to set up a consultation with Dr. Ye.

What to Expect With Root Canal Therapy

At Boston Post Dental & Implants, we understand that undergoing a root canal can be nerve-wracking, That’s why Dr. Ye focuses on educating patients throughout the entire process and going the extra mile to ensure they’re comfortable.

Before the procedure, one of our Sudbury dentists will take an in-depth X-ray to determine the severity of the infection. We’ll also administer local anesthesia to numb the area around the tooth to ensure you feel no pain. Once your tooth is numb, Dr. Ye will gently remove the infected pulp, decayed nerve tissues, and other debris.

The inner tooth cavity is then cleaned and sealed off to prevent any further infection. The empty pulp chamber and root canals will then be filled with a rubber-based material known as gutta-percha. Dr. Ye will later place a composite resin filling over the access hole for maximum protection.
