The Pain.
Dude, you're a mess. ;-)
A couple of years ago I had a wisdom tooth that was in bad shape... I made an appointment to see the dentist, they couldn't see me for a couple of days. So one day I was eating something when I heard "crack" inside my head and felt something in my mouth. A piece of the tooth had broken, and I wound up with an exposed nerve in that tooth.
It hurt to BREATHE. I couldn't eat, couldn't drink, could barely think. I found another dentist that would see me right away.
When he started digging into my gums to pull the tooth out, my brain completely shut off and I went out like a light. Next thing I recall was the dental assistant holding smelling salts under my nose, she said my eyes unfocused, rolled back up into my head and I was out. Good thing, she said, it took about 15 minutes to get the tooth out.
That sucked.
