In the news of late was mention of the use of dental xrays and the frequency with which they should be taken. We recommend having cavity detecting bite-wing radiographs and periapicals done once per year, and a full set of radiographs once every three years (which we do on both my own family, staff, and myself).
Please remember that we always use a lead shield over the body, which includes a thyroid collar. Additionally, we use digital xrays, which have 90% less radiation than conventional radiographs. The amount of exposure has been compared by scientists to less than 3 minutes in the sun! Environmentally, the digital xrays save on the waste produced by conventional radiographs, as there is no lead foil, cardboard, or developing and fixing solution released into or on top of our earth.
