Because there is usually an underlying inflammatory condition or chronic infection when you need a root canal, it is normal for there to be some discomfort afterwards. Usually this is noticed while chewing or the area may feel 'bruised'. Expect that the tooth will be tender to biting for several days after your treatment, and it may feel “different” for several months after the procedure. For most cases, the discomfort is managed with over the counter anti-inflammatory medications such as ibuprofen, Advil, or Aleve. We usually recommend that you take one of these medications before your anesthetic wears off. Tylenol is not an anti-inflammatory, but is recommended if you cannot tolerate or have been advised by your physician to avoid taking the anti-inflammatory medications. In some cases we may prescribe stronger medications. For management of moderate to severe pain, see our pain control strategies guide (link to our pain control strategies guide PDF). Occasionally, a “flare-up” can occur several days after your root canal therapy. These can sometimes occur in teeth that were not causing any pain prior to the treatment, but suddenly become symptomatic two or three days later. This can sometimes be accompanied by swelling of the gum or face. If this occurs, please call our office. We will evaluate your circumstance and recommend how to best manage the condition.
