In a dental clinic, a root canal is a common procedure aimed at treating a severely infected or damaged tooth. The process involves accessing the innermost part of the tooth, known as the pulp, which houses the nerve and blood vessels. Typically, a root canal becomes necessary when a tooth's pulp is inflamed or infected due to deep cavities, cracks, or trauma.

The procedure begins with the dentist administering local anesthesia to ensure the patient's comfort. Once numb, the dentist creates a small opening in the tooth to access the infected pulp. Specialized tools are then used to carefully remove the damaged tissue and clean the root canals, effectively eliminating any infection present.

After cleaning, the empty space within the tooth is filled with a biocompatible material, usually gutta-percha, to seal the canals and prevent further infection. In some cases, a temporary or permanent filling may be placed to restore the tooth's structural integrity. It's crucial to note that root canals are not painful due to the use of anesthesia, and the procedure alleviates the pain caused by the initial infection. Following the root canal, patients may experience mild discomfort or sensitivity, which can usually be managed with over-the-counter pain relievers. It is essential to attend follow-up appointments to ensure proper healing and, if necessary, discuss options for restoring the tooth, such as a dental crown, to protect it from further damage. Root canals have a high success rate and are an effective way to save a tooth that might otherwise need extraction. The procedure not only relieves pain but also helps maintain the natural structure of the tooth, preserving functionality and aesthetics. Regular dental check-ups and good oral hygiene practices are vital to preventing the need for root canals by addressing dental issues in their early stages.
