This is a focused beam of X-Ray particles through flesh and bone which produces an image on special film, showing the structure through which it passed. This gives the familiar black and white images that doctors and dentists use to diagnose problems.
X-rays are a necessary part of the diagnostic process, and not to use them could lead to undiagnosed disease. Without an X-ray of the whole tooth, and supporting bone and gum tissues, there is no real way to detect infection or pathology that requires attention.
In our office we use digital radiography which allows us to take X-rays using 50-70% less radiation versus conventional X-rays. Coupled with computer monitoring, digital x-ray technology allows us to enhance the images for better diagnosis of any dental concerns.
