I have a question about x-rays.
I had panoramic x-rays taken at my dentist, but now I moved and changed
dentists and wanted to have my old dentist forward x-rays to the new
dentist, so I wouldn't have to pay for them again and expose my head to
more radiation than necessary.
My old dentist says that they mailed originals to the insurance company
and didn't not keep the copies and that by law they are not required to
keep the copies.

I wanted to verify if that's correct and I can do anything?
