Root canal treatment, also known as endodontic therapy, is a dental procedure designed to save a tooth that is severely infected or damaged. Despite its reputation, a root canal is a crucial and often pain-relieving intervention that can preserve a natural tooth, preventing the need for extraction and facilitating continued oral health.
The need for a root canal arises when the pulp, the innermost part of the tooth containing nerves and blood vessels, becomes infected or inflamed. This infection can result from deep decay, repeated dental procedures on the same tooth, or traumatic injury. Symptoms may include severe toothache, swelling, sensitivity to hot and cold, and discomfort while chewing.
The root canal procedure typically involves several steps:
Diagnosis and X-rays: The dentist begins by examining the tooth and may take X-rays to assess the extent of the infection and the anatomy of the root canals.
Local Anesthesia: The affected tooth is numbed using local anesthesia to ensure the patient’s comfort during the procedure.
Access Opening: A small access hole is created in the tooth’s crown to reach the infected pulp.
Cleaning and Shaping: The infected or damaged pulp is carefully removed from the tooth’s interior. The root canals are then cleaned, shaped, and disinfected to eliminate bacteria.
Filling: After cleaning, the empty root canals are filled with a biocompatible material called gutta-percha to seal the space and prevent further infection.
Restoration: The access opening in the tooth is sealed with a temporary or permanent filling. In many cases, a crown is recommended to provide additional support and restore the tooth’s functionality and appearance.
Root canal treatment is highly successful and relieves pain associated with tooth infections. It allows patients to retain their natural teeth, avoiding the potential complications of tooth loss, such as shifting of adjacent teeth and difficulty in chewing.
While root canals have a historical association with discomfort, advancements in dental techniques and anesthesia have significantly improved patient experiences. Modern root canal treatments are often no more uncomfortable than having a standard dental filling.
