what is dental root canal

A dental root canal, also known as endodontic therapy, is a dental procedure that involves the treatment of an infected or damaged tooth pulp. The tooth pulp is the soft, inner part of the tooth that contains nerves, blood vessels, and connective tissues. When the pulp becomes infected or inflamed, it can cause severe pain and may lead to the formation of an abscess if left untreated.


During a root canal procedure, the dentist or endodontist (a specialist in root canal treatment) removes the infected or damaged pulp from the tooth. The steps involved in a typical root canal procedure are as follows:


Anesthesia: The area around the affected tooth is numbed with local anesthesia to ensure a painless procedure.


Access and Removal: The dentist creates an opening in the tooth, usually through the crown, to access the pulp chamber and root canals. Using specialized dental instruments, they carefully remove the infected pulp from the canals.


Cleaning and Shaping: The root canals are cleaned and shaped to remove any remaining infected tissue and to create space for filling material.


Disinfection: The canals are thoroughly disinfected with antimicrobial solutions to eliminate bacteria and prevent reinfection.


Filling: Once the canals are clean and shaped, they are filled with a biocompatible material called gutta-percha. This material seals the canals to prevent bacteria from re-entering.


Restoration: After the root canal is completed, the access opening in the tooth is sealed with a temporary filling. In most cases, a dental crown or other restoration is placed over the tooth to provide strength and protection.


The root canal procedure typically relieves pain and eliminates the infection within the tooth. It allows the natural tooth to be preserved and restores its function. With proper care, a tooth that has undergone a root canal can last for many years.


It's important to note that a root canal treatment is a specialized procedure that should be performed by a dentist or endodontist with expertise in endodontics. If you are experiencing tooth pain or suspect an infected tooth, it is recommended to consult with a dental professional for an examination and appropriate treatment options.
