The Benefits of Digital X-rays

Digital x-rays reduce radiation 80-90% compared to the already low exposure of traditional dental x-rays. Dental x-rays are a diagnostic tool in preventive dentistry that reveal areas not visible during a regular dental exam, and show problem areas may go undetected without the use of x-rays, such as abscesses, cysts, periodontal disease, decay that may not be clinically visible, and other bone or root abnormalities.

How often should dental x-rays be taken?

The need for dental x-rays depends on each patient’s individual dental health needs.  Your dentist will recommend necessary x-rays based upon the review of your medical and dental history, a dental exam, signs and symptoms, your age, and risk of disease.

A full mouth series of dental x-rays is recommended for new patients.  A full series is usually good for three to five years.  Bite-wing x-rays (x-rays of top and bottom teeth biting together) are taken at annual check-up visits and are recommended from anywhere between once or twice a year to once every two-three years.
