With modern techniques and anesthetics, most patients report that they are very comfortable during the procedure. For the first few days after treatment, your tooth may feel sensitive, especially if there was pain or infection before the procedure. This normal discomfort is to be expected, and can be relieved with over-the-counter or prescription medications. Your tooth may continue to feel slightly different from your other teeth for some time after your root canal treatment is completed. However, as with any dental treatment, if you have severe pain or pressure or pain that lasts more than a few days, call our office!
