Dude, if you get them pulled (which you should by the sounds of it) get the gas. You don't wanna be awake when they pull your wisdom teeth! It's like a fisherman wrestling with a great white, yanking those suckers out! Plus ya gotta love that cracking sound! If you're really lucky the tooth'll still be under the gum, and the dentist'll slice it open. hmm blood! Imo it's worth getting the gas. Sure it isn't the worst experience in the world, but why even put up with it when you don't have to?!
