How safe are dental X-rays? Do I have to get them?

We have digital x-ray machines that limit the radiation beam to the small area being x-rayed. Digital x-rays have 17 times less radiation than traditional film x-rays. We also have lead-lined aprons that protect the body from radiation. It’s important to have regular check-up x-rays to allow your dentist to detect disease and other conditions much sooner than by examination alone.
