In the words of Jordan G. "Why do we pay people money to inflict pain on us?"
No idea. We have this huge social pressure that if our teeth aren't white and straight, then we are unpopular, poor, and unattractive.
They hurt. You can't take them off. You can't eat your favorite foods. And the orthodontist I have cuts my gums on a regular basis.
Whine about them here!
