Hellooo. I'm an ex-braces wearer. I forgot how much it costs, cos my parents handled that.

Here's some of my experiences during that time.
- I never had ulcers caused by braces. (maybe I did.. but I forgot.)
- It'll only hurt for a few hours after tightening it every month.
- I didn't lose weight at all.
- Yesh, it kinda hurts when you just installed it.. i cried.
- I looked geeky. hahaa.
- I had a funny smile
- I actually missed having them after I took it off.

But it's worth it, in the end. I love my teeth now.

And about your vampire teeth thing, true or not.. I've not heard such thing before. And I sorta had that kinda teeth too. My dentist removed the teeth behind my 'vampire teeth', and pushed down my 'vampire teeth'. So prolly your dentist will do the same thing too.

Well, have fun. hehe.
