As to the x-ray portion of your question, my informal survey of the regulations of many states call for the dentist to provide copies of the x-rays to the patient upon request. In my experience, most dentists will gladly do this regardless whether there is a legal requirement to do so. So, I would suggest that you simply ask your dentist for a copy. As for additional options for getting a great looking smile, I would also consider porcelain veneers. Sometimes the procedure is called "instant ortho" because it has the effect of giving many people with twisted and rotated teeth a beautiful straight smile in only a couple of weeks. Good luck!
