A panoramic x-ray is a very impressive piece of imaging machinery in that it is capable of identifying many issues and structures that a normal x-ray is not. Initially you will stand with your chin on a small ledge. Once positioned in the machine, it will rotate around your entire head taking a full 360 degree view of the teeth, head, sinuses and bones.
The ability to view the full structure of your head as a whole is very informative to the dentist. It will allow them to see any potential problems and make sure that everything is functioning as it should be. The panorex is capable of viewing specific types of structural problems, infections or asymmetry among many others.
