A root canal is a treatment used to save a tooth that has been severely damaged or infected. The procedure involves removing the damaged or infected tissue from inside the tooth, and then filling and sealing the tooth. Root canals are usually successful, but there is always a small chance that the infection could return.
Most people can return to their normal activities after a root canal, including exercise and lifting weights. However, it is important to give your teeth and gums time to heal before returning to these activities. For most people, this means waiting at least 24 hours after the procedure before doing anything strenuous.
