Was scheduled to get four of six teeth drilled, turned out one of them didn't need it, so they only drilled three. The entire right side of my face from the nose down is numb, and I am currently in no pain. So what should I do in the three hours until it wears off?
I got teeth pulled out once, they injected so much numbing medicine it hurt after a while. I propose you get something seriously cold and press it on your numb side, freeze it to death! =D
Try using a straw to drink. I tried this after getting three teeth filled last fall. Hardcore fail. Actually, any action that involves pursing your lips and sucking will fail.
