Dear bigphil96b, It is not unusual for swelling to occur after the extraction  of four wisdom teeth. I would suggest that if the swelling doesn't go down that you see the doctor that extracted the teeth. Dry sockets are more common  in the lower jaw. There is acute pain (throbbing) that sometimes radiates into your ear. The cause is unknown, but the area should treated with a medicated dressing.
