I'm sure you've seen them in the pics I've posted. Really, they're not HORRIBLE, but they're a bit out there. My bottom row of teeth isn't bad at all, mostly just a liiiittle bit out of perfect straight order...hardly something to complain about.
The TOP row is a bit messed up. First off, I have an overbite that darn near overlaps my lower teeth so that closing my jaw comfortably to make my molars meet makes my top front teeth rest evenly in front of my lower ones. In addition, the incisors are a bit angled inwards towards my mouth a little bit, but the most noticable thing is my canines; they're kinda stuck out a little further than the rest of my teeth, which has led LOTS of people to make "vampire" comments.
Here's an older pic a lot of people have probably seen, shows the top row fairly well...
@Frank: Yeah, I'm supposed to have mine 2 to 2.5 years...
