Had all 4 wisdom teeth removed during my college years. The procedure itself was routine. The post surgery recovery was not.
I was left unattended for what they claim was a short period of time, while the anesthesia wore off. I came out of it sooner than expected, not fully knowing WTF was going on. I somehow got out of the chair, knocked over a tray full of dental tools, tripped and ended up on the floor crawling around on my hands and knees. Hearing all the commotion, the assistant came running into the room, flung the door open and whacked me in the head..... out like a light again. Woke up a short time later with a paramedic checking my vitals.
Oh yeah, later on I had to deal with 2 dry sockets.....fawk.
