My chin/jaw but it's crooked, which makes my mouth, chin, and teeth crooked as well. Any suggestion? (photos)

I'd like to know what it may be and what surgery I could get done to fix it. My chin slants to one side of my face instead of being symmetrical. My teeth don't line up well and my lips are slanted because of this as well. It's one of my biggest flaws and I hate pictures because of it. Any information you could give me would be great.
