A dental X-ray procedure does not presuppose any preparation. You will be taken to the radiology department and ushered into an office or dark room where the professional X-ray equipment is kept. The technician that is in charge will guide you through the process, just follow their instructions. You will stand still in front of a plate. Remove your earrings, metal objects, eyeglasses, and other jewellery from the area that will be scanned beforehand.
