Wisdom tooth extraction is a surgical procedure that requires some post-operative care to reduce the chance of infection or other complications. Immediately after surgery, a gauze pad will be placed over the extraction site, which should not be removed for at least 30 minutes, then discarded. Refrain from drinking through a straw, rinsing the mouth or smoking for at least 24 hours to ensure that you do not dislodge the blood clot that has formed. Limit your activities that day. You can resume your regular activities the following day. Take the pain medication as prescribed to reduce the amount of discomfort you feel after the local anesthetic wears off. Call the office if you experience fever, nausea or vomiting, swelling or pain that gets worse with time instead of better.
