Digital x-rays use a small sensor on the end of a wire that is placed inside the patient’s mouth and moved into position according to what part of the teeth the dentist wants to x-ray. Then the x-ray is taken and immediately appears on the dentist’s computer screen. Additional digital x-rays can be taken by simply repositioning the sensor and pressing a button. The patient does not need to move, and there is no waiting for the films to develop.

Once the x-rays are taken, the dentist can enlarge the images on the computer screen, which allows both the dentist and the patient to more easily see any problems that may need attention. The images can also be saved in the computer, creating an electronic record that is easy to store, retrieve, and transfer as needed. In addition, there is up to 90 percent less radiation exposure with digital x-rays as opposed to traditional systems.
