A coupla years ago, I was working on a tractor, pulling powerslide wheel clamps, to lube them up, IIRR, anyway, cant really describe it, but I didn't feel right, couldn't pin it down to anything specific, but anyway, the wrench slipped off the bolt, and my head dropped down, hitting the front of my chin, on a tire cleat, hit was just below the tooth root line. Felt like a semaphore signal of pain, de deet deet dah deet, OWWW! turns out I had an abscess, under one of the center lower teeth. Lesson learned, don't mess with tooth pain! If it hurts Monday, I would go get it looked at.
