The physical process for digital radiography is actually similar to traditional dental X-rays that use film: With digital radiography, your dentist inserts a sensor into your mouth to capture images of your teeth — but that’s where the similarities between conventional and digital dental X-rays end. Although it resembles the film used for bitewings and other X-rays, the digital sensor is electronic and connected to a computer. Once the X-ray is taken, the image is projected on a screen for your dentist to view.
Less Radiation — The equipment used in digital radiography exposes dental patients to much less radiation. In fact, digital X-rays use up to 90 percent less radiation than film X-rays. While conventional dental X-rays are relatively safe, digital radiography is an excellent option for those who take X-rays on a regular basis or for those who are concerned about radiation.
