When your root canal procedure is complete, the tooth is in the best environment to heal efficiently. All infection and decay have been removed, and the root canals have been sealed to prevent the entry of bacteria or debris. The temporary crown that's affixed over the tooth at the end of the procedure protects it from further damage. Now, it's time to just let your body engage in its repair process to reduce minor swelling and soreness. This usually doesn't take longer than a week. You don't have to arrange time off work for your root canal recovery. Simply going home to rest after your appointment should be sufficient. You may feel well enough to return to work as soon as the day after your procedure, taking precautions with your diet and pain management.
