Dental x-rays let your dentist see what the eye cannot: cavities between teeth, infection at the root, bone loss from gum disease, and the position of wisdom teeth. Without them, small problems stay hidden until they become painful.
Digital x-rays use up to 80 percent less radiation than older film, and a lead apron adds further protection. The tiny dose from a routine set is comparable to a few hours of the natural background radiation we all receive every day.
