My worst memories growing up are when I had my braces on. My mouth was always hurting. 
i know they are a device to align and straighten teeth and help position them, why did it hurt so much?
My teeth were messed up. I looked like some sort of animal. I guess it was because the braces were pulling my teeth together. I wonder how many people have to ware them?
People dont have to, its their choice, everybody wants to be beautiful  according to scholars and historians, braces date back to ancient times.
