Digital x-rays are x-ray images that use electronic technology to capture images instead of the radiation that is used for traditional x-rays. An electronic sensor, which is attached to a computer, is placed in your mouth to capture the image. Digital x-rays show us your teeth, the areas in between, and the areas below your gumline. X-rays are an important component of your routine dental care, taken periodically to monitor your oral health and ensure there are no issues developing. They are also important for diagnosing a wide variety of different oral health issues.
