Do I need braces? (Photo)

I believe I have an overbite, small gaps, and a crooked tooth (the one left of the front teeth.) I think I should get them because when I get older I want to be an orthodontist and a great smile will be a big part of my job. I also have super tiny teeth, I chew on my cheeks, my teeth always hurt, I have really pointy "fangs," and I lost all my teeth super early. I am not sure what to do because my mom is unsure as well, some professional help would be appriciated
