The amount of radiation you receive in one dental x-ray is approximately 1/8th the amount you receive in a single cross-country plane flight.
I mean, you still don't want to overdo it. All things being equal, you want to limit your exposure to ionizing radiation across the board. But dental x-rays generally aren't a public health menace, and they're seldom overprescribed to a dangerous degree. I'd much rather get a dental x-ray that prevents costly and dangerous dental disease in the proximate future, given the fairly low dosage involved.
