root canal procedure is typically performed by a dentist or endodontist to treat a tooth that has become infected or severely decayed. The procedure involves removing the infected or damaged pulp from the inside of the tooth, cleaning and disinfecting the area, and then filling and sealing the tooth to prevent further infection.

During the procedure, the dentist will first numb the area around the tooth with a local anesthetic to ensure the patient is comfortable. They will then create a small opening in the tooth to access the pulp chamber and root canals. Using specialized tools, the dentist will carefully remove the infected or damaged pulp and clean the inside of the tooth to remove any bacteria or debris.

Once the tooth has been thoroughly cleaned, the dentist will fill the root canals with a rubber-like material called gutta-percha to seal them off and prevent any further infection. The opening in the tooth will then be sealed with a temporary or permanent filling to protect the tooth and restore its function.

After the root canal procedure, patients may experience some discomfort or sensitivity in the treated tooth, which can usually be managed with over-the-counter pain medication. It is important to follow any post-operative instructions provided by the dentist, such as avoiding chewing on the treated tooth until it has been fully restored with a permanent filling or crown.

Overall, a root canal procedure is a common and effective treatment for saving a tooth that would otherwise need to be extracted due to infection or decay. With proper care and maintenance, a tooth that has undergone a root canal can last a lifetime.
