How to Get Free or Cheap Braces I Am Really in Need of Them Bad?

I am a low income and am 20 years old. The only kind of insurance that I have is medicaid living in Idaho. I have about the most aweful crooket teeth that I've seen in person, have had them since I was 10 years old! My mother was never able to afford them. Growing up I got picked on a lot as the crooket teeth girl but I learn to ignore it. Now that I'm older, I feel its now starting to get in the way of finding a career! I really wish I would've had a bigger jaw, my teeth are just over crowded
