Typically, most X-rays require patients to hold or bite down on a piece of plastic with X-ray film in the center.
Some dentists are now using digital X-rays. To take a digital X-ray, your dentist will place a sensor on the tooth that looks like a piece of film. Once the picture is taken, your dentist can adjust the contrast and brightness of the image to find even the smallest area of decay. Other benefits of digital X-rays are decreased exposure to radiation and reduced time to develop photos, which helps eliminate treatment disruptions.
