How do I fix my crooked smile/teeth and lip?

I can't stand how this looks and I really want to know how to fix it and know exactly what the problem is. I know I have extremley crooked teeth and I think I have an overbite. Could this just be treated with braces or would I need more work? Like Jaw surgery? Nobody has ever pointed it out to me and when I look in the mirror i dont see anything crooked at all not even when I smile (expect for my teeth of course) it's when Only when I take pictures that I myself notice it.
