A root canal, also known as endodontic therapy, is a dental procedure designed to save a tooth that is severely infected or damaged. It involves removing the damaged or infected pulp, cleaning and disinfecting the interior of the tooth, and then sealing it to prevent further infection. The term “root canal” also refers to the natural cavity within the center of the tooth.

Why Are Root Canals Needed?

Root canals are typically recommended when the pulp of a tooth becomes inflamed or infected. This can occur due to various reasons, including:

1. Deep Decay: If tooth decay reaches the pulp, it can lead to infection and pain.

2. Trauma: A traumatic injury to the tooth can damage the pulp, leading to infection.

3. Cracks or Fractures: Cracks or fractures in a tooth can expose the pulp to bacteria, causing infection.

4. Repeated Dental Procedures: Sometimes, multiple dental procedures on the same tooth can weaken it, making it susceptible to infection.

The Root Canal Procedure

A root canal typically involves the following steps:

1. Diagnosis: The dentist will take X-rays to determine the extent of the infection and to assess the condition of the surrounding bone.

2. Anesthesia: Local anesthesia is administered to numb the tooth and the surrounding area, ensuring the patient is comfortable throughout the procedure.

3. Access Opening: A small access hole is created in the crown of the tooth to reach the pulp.

4. Pulp Removal: The infected or damaged pulp is carefully removed using specialized instruments.

5. Cleaning and Shaping: The interior of the tooth is cleaned, disinfected, and shaped to prepare it for sealing.

6. Sealing: Once the tooth is thoroughly cleaned and shaped, it is sealed with a biocompatible material called gutta-percha to prevent further infection.

7. Restoration: In most cases, a crown is placed on the treated tooth to restore its strength and appearance.
