For a couple of days now, I have had this really bad pain in the bottom, left side area. This pain is throbbing, and it fluctuates between mild and moderate pain. One weird thing is that the pain is relieved when I drink something cold. My teeth have always been sensitive to hot/cold, so I am baffled. I need to go to the dentist because I know I have cavities. This pain just doesn't feel like its coming from 1 tooth; it feels like its my whole row of teeth on the bottom left side. In other words, I can't pinpoint the cause. I have been taking so much tylenol, and it helps. Sometimes I get the pain intensely, it hurts for a few minutes then it can go hours without, and then later hurts again. I do not have pain with biting down.
