Allow me to be the gloomcloud. I never had braces due to cost, and I'll likely have a jumble of teeth for the rest of my life. I think it'd look epic for a creature cosplay, but for regular people (and, you know, life) it looks like I have weird fangs when I smile.
So do your braces, follow everyone's suggestions, and have a brilliant set of chompers. It'll be worth it in the long run.
