In the past, dentists would use film X-rays to view the inside of your teeth and the area of your mouth that lies below the gums. The downsides were that it took awhile to develop the images, making visits last longer than necessary, and the pictures would come out unclear, which could result in inaccurate diagnoses. Today, we utilize all-digital X-ray imaging that reduces radiation exposure by up to 90 percent and makes each of your checkups more accurate and faster.
