Root canal treatment, also known as endodontic treatment, is a dental procedure that involves removing the infected or damaged pulp from a tooth’s root canal chamber. The root canal chamber is located at the centre of each tooth and contains nerves, blood vessels, and connective tissue. If the pulp becomes inflamed or infected, it can cause severe pain and sensitivity, and in some cases, it may result in the loss of the tooth. During a root canal treatment, the dentist will numb the tooth and surrounding area with a local anaesthetic. They will then make a small hole in the top of the tooth to access the root canal chamber. Next, they will use specialized tools to remove the infected or damaged pulp and clean the canal thoroughly. Once the canal is clean, the dentist will fill it with a biocompatible material, such as gutta-percha, to seal it off and prevent further infection. Finally, they may place a crown or other type of restoration over the treated tooth to protect it and restore its function. Root canal treatment is typically performed over the course of one or two appointments, depending on the severity of the infection or damage. It is generally considered a safe and effective way to save a tooth that would otherwise need to be extracted. After the procedure, patients may experience some mild discomfort or sensitivity, but this can usually be managed with over-the-counter pain relievers and should subside within a few days. Proper oral hygiene, including brushing and flossing regularly, can help to prevent future dental problems and ensure the long-term success of the root canal treatment.
