just got mine out today and it is not bad at all. i mean, ive hit a tree before and had a tube in my chest for 10 days i think i can take 4 teeth being cut out. get the gas, and if you can ask for extra numbing stuff because that will take the pain away longer after you leave.  only take the pain medicine if you absolutely need to because im sure there will be times a few days down the road when you will need it more.
