A root canal, also known as endodontic therapy, is a dental procedure that is performed to save a tooth that has become infected or inflamed in the pulp, which is the soft tissue inside the tooth. The procedure involves removing the infected or inflamed tissue, cleaning and shaping the root canal system, and filling the canal with a special material to prevent further infection.

Here are some important aspects of root canal treatment:

• Diagnosis: If you are experiencing severe tooth pain, sensitivity to hot and cold temperatures, swelling or tenderness in the gums, or a darkening or discoloration of the tooth, your dentist may recommend a root canal.
• Procedure: The root canal procedure is typically performed under local anesthesia to ensure that you are comfortable and pain-free throughout the procedure. The dentist will make a small opening in the top of the tooth to access the pulp and will remove the infected or inflamed tissue.
• Cleaning and shaping: Once the infected or inflamed tissue is removed, the dentist will clean and shape the root canal system using small instruments. This is done to remove any remaining bacteria and to ensure that the canal is free of debris.
• Filling the canal:Once the canal is cleaned and shaped, the dentist will fill it with a special material called gutta-percha to seal the canal and prevent further infection.
• Restoration: After the root canal procedure, the tooth will be restored with a filling or crown to protect it and restore its function.

Root canal treatment is a highly effective way to save a damaged or infected tooth and prevent the need for extraction. With proper care and maintenance, a tooth that has undergone root canal treatment can last a lifetime.
