My teeth line up and my jaw/chin is crooked. What kind of procedures can give me a straight smile? (Photo)

My upper and lower teeth do not line up and meet properly. Also my jaw and chin are slanted you can really tell when I smile I look ridiculous. My jaws often hurt and I always have head aches (not sure if that is due to my mouth issue) Do I have any options? What kind of procedures can give me a straight smile? Also I have 10 veneers on top will that get in the way of a surgery? Also my chin was crooked before the veneers. Thanks so much for your time please help!!!
