A root canal is a dental procedure that repairs and saves a badly damaged or infected tooth instead of removing it. The term "root canal" comes from the cleaning of the canals inside a tooth's root.

Why is a root canal necessary? Root canal treatment is necessary when the tooth's pulp, the soft tissue inside the tooth that contains nerves and blood vessels, becomes infected or inflamed.

This can happen as a result of:

Deep decay

Trauma

Repeat dental procedures

If a tooth has had multiple fillings or other dental work, the pulp may become irritated and inflamed.

What happens during a root canal? A root canal is typically performed by an endodontist, a dentist who specializes in treating the pulp of the tooth. Here's what you can expect during a root canal:

1. Anesthesia: The dentist will numb the area around the tooth with a local anesthetic. 2. Access opening: The dentist will create a small opening in the top of the tooth to access the pulp chamber.

1. Cleaning and shaping the canals: The dentist will use small instruments to remove the infected or inflamed pulp from the root canals. The canals will then be shaped to allow for filling.

1. Filling the canals: The cleaned and shaped canals will be filled with a rubber-like material called gutta-percha.

2. Sealing the tooth: The dentist will seal the opening in the tooth with a filling or crown.

Benefits of a root canal There are many benefits to having a root canal, including:

Saves your tooth: A root canal can save a tooth that would otherwise need to be extracted. – Relieves pain: A root canal can relieve pain caused by an infected or inflamed tooth.
