It is normal to feel some tenderness in the area for a few days after your root canal treatment as your body undergoes the natural healing process. You may also feel some tenderness in your jaw from keeping it open for an extended period of time. These symptoms are temporary and usually respond very well to over-the-counter pain medications. Your tooth may continue to feel slightly different from your other teeth for some time after your root canal treatment has been completed. However, if you have severe pain or pressure that lasts more than a few days, contact us.
