I had four impacted wisdom teeth pulled out when I was twenty. The first thing that sucks was that (as a smoker at the time) you can't have any cigarettes. You also have to eat soft foods and leave cotton in your mouth for awhile. You'll be on pain pills for a bit, and things won't feel right in your mouth for a few days, at least. Then, your girlfriend of three years breaks up with you ten minutes before her new boyfriend (a guy she slept with while you were at the dentist) shows up to move in. See, he doesn't have anywhere else to stay, and so he has to move in, and since she pays half the rent, this is somehow acceptable. Then they steal your last condom from your desk while you are crying on the porch, unsure of what just happened, and you go back inside and listen to them have sex through the thin wall separating you from the second bedroom. That night she comes into your room and wakes you up to tell you that you're still her best friend. As soon as you grasp at the sliver of hope, she starts talking about how this new guy makes her orgasm, something she was never able to achieve with you. When you tell her that you don't want to talk about that with her, she cries and says, "well who else am I supposed to talk to about it? You're my best friend!" The next day you threaten to call the cops in some vain attempt at sorting out this bizarre and awful situation. She moves out with him, but only a few apartments away, so of course, and against your better judgement, you start sleeping with her again. Two days later the new boyfriend catches you and gets in a fistfight with you. He punches you right in the teeth, and the pain pills the dentist gave you just aren't enough to relieve the pain of your newly swollen jaw or your broken heart. You go outside and have a cigarette, even though you weren't supposed to, and it causes your wounds to open and your gums to bleed. But at that point, who cares. What's the point of anything, anyway.
Yeah, don't get your wisdom teeth removed. It can sort of suck.
