Do digital X-rays use lower amounts of radiation?

A digital X-ray requires less radiation to capture a high-resolution image than the traditional X-rays used a few decades ago. Depending on the type of film, equipment, and image being taken, it may be as much as a 90% reduction in exposure. As such, it’s safe to say that today’s dental X-rays are extremely safe.

Compared to not getting dental X-rays, the tiny amount of radiation exposure is an important trade off. Why? Because diagnostic imaging allows dentists to see inside and around the tooth structures where pathology (such as bone loss, oral cancer, or tooth decay) commonly lurk. Diagnosing them as early as possible allows for less-invasive and more cost-effective treatments. Otherwise, such problems can’t be detected until they’ve reached an advanced state that requires more aggressive therapies to manage.
