I'm getting all my info from hubby, so i'll give you what he tells me.
1: He got enough anasthesia to only feel pressure as they were pulled out, but his bottom teeth were sideways so they actually had to drill in and take them out in pieces. The cloth covering his eyes was slipping, and he saw pieces of skin "flying everywhere," so unless you're knocked out you might not want to see what they're doing. *L*
2: He doesnt now, he had his eyes covered. he only heard the drill.
3: Wherever they need to to get the teeth out.
4: Lots of pressure on the lower teeth, normal yanking on the uppers, but it may vary depending on how good or bad your teeth are.
5: Depends on how complicated it is for them to extract them. He didn't really take note of the time.
It's really afterward what you gotta worry about. They give you nice 'happy pills' to ease the pain, and you gotta change your gauze every now and then because it will get soaked in blood (tryring not to scare you, honest. ^^; ). You won't be hungry because of the pain of chewing, but if you do get hungry eat soft things like mashed potatoes and soup. After the pain is gone, usually there are holes left by the teeth, and they give you this weird syringe to spray water into the holes to get food particles out that leaves your breath foul if left to rot.
There is an ailment you gotta watch out for; called Dry Socket. It is the worst pain you can experienece, so says a friend of hubby's. He said, "I would not wish this pain on my worst enemy." How to prevent it is to simply follow the dentist's directions, and you should be pretty safe.
I hope this helped. :3
