TIME HELPS....Most swelling starts to subside after 72 hrs. FIRST day after surgery, put a cold compress on the swollen area. You can purchase a cold gel pack from Walgreens/CVS, or you can use a bag of frozen vegetables. You can also make a cold compress by wrapping ice cubes in a towel (it can get messy). Take a styrofoam cup and place water in it, freeze it... once frozen the styrofoam acts like an insulator from the cold so that you can hold it. Do NOT use dry ice.Be sure to keep the cold compress there for 10 minutes. Take it off for 10 minutes, then put it back on for another 10 minutes; rotate/repeat; Do this over and over again for the first 24 hours after surgery, if possible.On the SECOND day after surgery, put something warm on the swollen area. You can make a warm compress by wrapping a hot water bottle or a heating pad in a towel. Placing a moist towel in the microwave for a FEW seconds (be careful not to overheat). The warmth will increase blood flow or circulation and bring down the swelling. Do not use anything hot enough to burn your skin. Call your dentist or oral surgeon if the swelling continues to get WORSE 72 hours after surgery, or if the swelling does not go down within 7 days after surgery. Call 911 if you cannot breath/airway narrows.Steroids can be prescribed by your doctor to minimize swelling.Positioning your head so it's blood pressure is slightly reduced can help to minimize the amount of swelling that occurs. The general idea is to keep your "head above your heart."Sit up right (or recline); When lying down, prop yourself up by using 2 or 3 pillowsAs with all information, consult your dentist prior to making any decisions.Hope that helps.
