Dr Mike Barr is an excellent cosmetic dentist in Florida with whom Pat and I are friendly. He has a very good blog, and he recently wrote a post on dental x rays and cancer. Here’s an excerpt:

“The truth is that dental x-rays are the LOWEST source of ionizing radiation from medical AND natural sources. A series of four check-up bitewings is the same as a 2-hour flight in a passenger jet. Likewise, the radiation you receive by living inside a concrete block house (most modern houses in Florida) for one year, is about the same as you get from a Full Mouth Series (18 films) of dental x-rays. A chest CT scan is 700 times the radiation of a dental x-ray. These are verifiable, measurable facts.”
