question: My boyfriend was complaining that his partially capped front upper tooth was hurting him the other day. He said cold makes it feel alot better. We noticed a little swelling in his upper lip last night. Today he woke up and his upper lip is now severely swollen along with the left side of his face from his lip up to just under his left eye. He said his tooth still hurts alittle but not a ton. He is having trouble chewing.  I saw pictures of a abcsessed tooth and dont see any signs of one on him. He is also not allergic to anything that we kno of and hasnt eaten, drank, or taken anything odd.
