For the first few days following the completion of a root canal, the tooth may feel sensitive due to natural tissue inflammation, especially if there was pain or infection before the procedure. This sensitivity or discomfort usually can be controlled with over-the-counter pain medications such as ibuprofen (Advil, Motrin) or naproxen (Aleve). Most patients can return to their normal activities the next day.
Until your root canal procedure is completely finished — that is to say, the permanent filling is in place and/or the crown, it’s wise to minimize chewing on the tooth under repair. This step will help avoid re-contamination of the interior of the tooth and also may prevent a fragile tooth from breaking before the tooth can be fully restored. As far as oral health care is concerned, brush, floss, and use an antiseptic mouthwash as you regularly would and see your dentist at normally scheduled intervals.
