Had an abscessed tooth so bad once, I was SOBBING from the pain and could not stop. Ended up going to ER in the middle of the night, the doc gave me antibiotics immediately and a script for Tylenol 3's. They worked, but I could not get them until the next day. I wanted to scream and shoot myself in the face to make it stop. It was AWFUL. As soon as the antibiotics knocked the infection down I had that sucker pulled.
