How many dental x-rays can i take in a year before the radiation adds up?

Wrong question.: All x-rays added together have cumulative toxicity, long-term carcinogenicity. Avoid unecessary x-rays whenever possible. Drs. And dentists with there personal machines look at these devices as a way to print money.

Even one adds up!: Dental x-rays have been shown to more than double the risk of certain brain tumors! there is no "safe" dose of radiation, as even a small dose can create problems, but the risks rise with higher doses. The risk from a single x-ray is small but children should not get dental x-rays in most cases.Only have x-rays if essential. See http://www.Naturalnews.Com/035625_x-rays_brain_tumors_dentistry.Html.
