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 45 minutes, and then discarded after that. Refrain from drinking from a straw, smoking, or rinsing the mouth to ensure that you do not dislodge the blood clot that has formed. Any activity that will cause a puckering effect or suction effect in the mouth should be avoided. Limit your activities that day. You can resume your regular activities the following day. Smoking should be avoided for at least 48 hours after surgery. Take the pain medication as prescribed to reduce the amount of discomfort you feel after the local anesthetic wears off. Apply ice pack to the region (not directly to face) to reduce swelling and bruising after procedure.
