[???]

what do i do?

my teeth aren't terribly crocked, but i know it will get worse if i don't fix this now.

this is how my top teeth look like (with one tooth slightly forward) http://news.bbc.co.uk/olmedia/895000/images/_896134_teeth150.jpg

and my bottom teeth are crocked like this: http://www.public.iastate.edu/~lora/lora_teeth2.JPG

but they are not sticking up

how much will it take to fix this? (about)
how long do i have to wear the braces? (about)
what do you recommend i should do about the financial problems of me getting braces?

and please tell me if your a dentist so i can see which advice would be most accurate
im 15.. and im in school

and those arn't my teeth

those are just examples
