I've only had one out, about 4-5 years ago. I was awake for it, and I've got a pretty small mouth so I knew it would be pretty awkward to get out.
But yeah, with the pain killers it doesn't hurt, its just a bit uncomfortable as I always find at the Dentist sat there for 30 mins with your mouth stretched wide open.
It took him a little while to get it out at the end, actually I think he was quite new and had to go get a more experienced Dentist to do it for him, haha.
Hearing it crack out at the end made me wince a bit, but yeah it didn't hurt at all, looking bad it wasn't really anything major really.
I know some people have it worsse, but I'd say ignore all the horror stories and don't worry. Let's face it- it needs to be done, you are gonna have it done, it's not gonna kill you or give you any lasting ill-effects, so don't fret it
