Well last year I had all four of them pulled out in one shot, you should have seen my x-rays, all four were growing completely sideways therefore pushing all my other teeth (forward)together, expect a lot of blood gashing out of your mouth when you first wake up.
Because of all the painkillers I thought I was ok so I was walking around, talking and eating straight after, when I opened my mouth too wide and heard one of my stitches rip out from my gum, I blacked out, collapsed and bashed the side of my head on the floor, after that I stayed in bed till it healed... thank-god they put you to sleep now a days, unlike when my mum had of hers out, she was completely awake and the dentist was pulling it out with pliers while the nurse was trying to hold her head against the chair.

Overall it wasn't that bad, the painkillers they give you are pretty full on.
