The amount of radiation exposure on a dental x-ray is still tiny though, we are talking like 5 or 6 orders of magnitude lower than radiation poisoning thresholds. Plus there is extensive epidemiological data about their safety.
Agreed. My problem is that every dental association I’m aware of recommends dental X-rays on an individual, clinically justified basis and not a regular schedule. There are very few dental scenarios requiring yearly X-rays. They do them to get more money.
