There is very low radiation exposure. However, no one should receive more radiation than necessary. A lead apron can be used to cover the body and reduce radiation exposure. Pregnant women should not have x-rays taken unless absolutely necessary.
Dental x-rays can reveal dental cavities (tooth decay) before they are visible even to the dentist. Many dentists will take yearly bitewings to catch the early development of cavities.
