Dental x-rays are considered safe for children. The amount of radiation emitted from dental x-rays is minimal and would rarely cause any health problems. The benefits of dental x-rays far outweigh the risks. Dental x-rays allow us to detect tooth decay, infections, and other problems that cannot be seen with the naked eye. Early detection and treatment of these problems can save your child a lot of pain and suffering in the future. If you have any concerns about the safety of dental x-rays, please feel free to discuss them with your dentist.
