The physical process for digital radiography is similar to traditional dental X-rays that use film: With digital radiography, your dentist inserts a sensor into your mouth to capture images of your teeth — but that’s where the similarities between conventional and digital dental X-rays end
Dental x-rays are a common diagnostic procedure that is considered extremely safe. Digital dental x-rays have very low doses of radiation, producing just a fraction of what you are exposed to in other imaging procedures.
Not only do digital x-rays expose patients and staff to up to 90% less radiation than traditional film x-rays, but they are also better for the environment because they don’t require developing. They can be viewed on a computer monitor within seconds after taking the image.
