Parents ask us about x-rays all the time, and it is a fair question. Here is the honest answer. Once the back molars are touching each other, the surfaces between them cannot be seen during an exam, and that is exactly where cavities like to start in kids. By the time decay between two teeth is visible or hurting, it has usually gone through the enamel and into the softer layer underneath, which is the difference between a small filling and a crown. On the safety side: a standard set of four digital bitewing images is roughly the same exposure as a day or two of the natural background radiation everyone gets just from being alive, and less than a cross country flight. We use digital sensors, a lead apron, and a thyroid collar, and we take them based on your child's actual cavity risk rather than on a fixed schedule. If you ever want to see what we are looking at, ask us to turn the screen. We are happy to walk you through it.
