Why are wisdom teeth called "wisdom" teeth? Why aren't they called useless, good for nothing, going to cost you $1,600.00, wish you got them out twenty years ago when the parents could have paid for them teeth. I'm having mine out next Friday and am confused about something. What's so fracking wise about the teeth in the back of your mouth that are good for nothing but giving you grief? Most of the time they don't even come in all the way and they can get compacted (and no I'm not talking about the Broke Back kind of compacted). Nothing is wise about them, so why the hell are the called wisdom teeth? Do they give you wisdom when they are in your mouth or do you gain wisdom when they are taken out? I'm hoping for the latter.
