Edit: Oh and it varies in terms of how far your teeth are out. If they are poking out, likely less time. With me, they took them out before it got that far, so they had to scraqe away gum. Lovely thinking about that... But it really didn't hurt.
I agree. If given the choice, I would always choose sedation. Even if it isn't painful, the sounds you hear are enough to make my skin crawl. My wisdom teeth were coming out of my gums when I had them out. My parents decided that while I had to get mine out, my brothers should get there's out as long as we're down there. At the time, there was no need for either of my brothers to have their WT removed.
We were all sedated, so I'll just describe the aftermath. Mine came out like a charm. I had no swelling and healed fairly quickly.
My brothers had huge swelling and took a lot longer for their gums to heal. Not only that, but we were given our wisdom teeth afterwards, and holy cow!
Mine came out perfectly whole and looked like teeth. Each tooth of my brothers were broken up into 4 or so pieces. So think about it, they couldn't come out whole, so the doctor had to break apart the teeth while they were still in the gums.
It seriously looked like they were broken up using pliers and then yanked out. Try to imagine the sound of a tooth being crushed apart with pliers or something. I didn't hear it, but I would be so freaked out if I had.
