Root canal treatment, also known as endodontic treatment, is a dental procedure used to repair and save a severely damaged or infected tooth. The treatment involves removing the infected or inflamed pulp (soft tissue inside the tooth), cleaning and disinfecting the root canals, and then sealing them to prevent further infection.

Root canal treatment becomes necessary when the dental pulp inside a tooth becomes infected or inflamed due to deep decay, repeated dental procedures on the tooth, cracks, chips, or traumatic injuries. If left untreated, the infection can spread, leading to severe pain and the possible loss of the tooth.

Common signs that you may need root canal treatment include persistent toothache, sensitivity to hot or cold temperatures, swelling of the gums, darkening of the tooth, and the presence of a pimple on the gum near the affected tooth. However, a proper diagnosis by a dentist is essential to determine the need for a root canal.

Contrary to popular belief, root canal treatment is not as painful as its reputation suggests. The procedure is performed under local anesthesia, ensuring that the patient does not experience pain during the treatment. After the procedure, some post-operative discomfort is normal, but this can be managed with over-the-counter pain medications.

The duration of root canal treatment varies depending on the complexity of the case and the tooth's condition. Generally, it can be completed in one to three appointments, with each appointment lasting around 1 to 2 hours.
