Tooth extraction, performed by a dentist, consists in extracting a tooth under local anesthesia. A dental extraction is generally done when a tooth is too decayed to be treated. It can also be to remove a tooth not visible, even under the gum (impacted tooth) as a wisdom tooth.
1 hour before your appointment, you can take a pill of Ibuprofen (advil, motrin…).
Once the anesthetic (numbing) loses its effect, it is normal to feel pain. The period of most intense pain could last 24 to 48 hours after surgery. Pain or discomfort at the site of the operation may last for 3 to 5 days. The pain will be more or less pronounced depending on the person and from one operation to another.
It is important that you rest. The more you move, the more you may feel pain. Call your dentist or oral surgeon if the pain does not decrease after 48 hours, or at any time if you believe that there is a problem.
