I had to have braces when i was in primary school
I had sharks teeth (my big and little set all grew at once making 2 rows of teeth).
I had to have all my baby teeth taken out and my adult teeth straitened with braces. They were hidious, you couldnt choose your colour back then though, they had to be black :(
My teeth are good now though, besides the years of smoking that has stained then, but ive given up smoking now so a polish will sort them out.
On the bad side, ive not been dentists since i was 16....im nearly 22 now :S
