The safety of dental x-rays is a common concern of patients. The American and Canadian dental associations have guidelines for dental professionals to follow to make them as safe as possible. There is a general principle in radiation safety called ALARA – as low as reasonably achievable. Dental professionals use the lowest possible dose and to limit exposure whenever possible to be able to treat patients safely and efficiently. Digital x-rays in most offices use up to 80% less radiation than traditional film x-rays.
Dental x-rays or radiographs are pictures that show the anatomy of the teeth, surrounding bone and soft tissues in areas of the mouth.
