Yes, radiation from dental X-rays is low enough to be considered safe for routine care, and the American Dental Association recommends routine X-rays for healthy adults only every two to three years. We take X-rays only when they are needed to find problems a visual exam can’t, and we follow safety steps to keep exposure as low as possible.
How often dental X-rays are taken?
How often dental X-rays are taken is based on risk for infection, physical symptoms, and clinical findings. The American Dental Association (ADA) is a governing body over the dental profession. The ADA states, “ . . . healthy adults receive routine mouth X-rays every two to three years. Dental X-rays are recommended every one to two years for children and every 1.5 to three years for teens. Children often require more X-rays than adults because of their developing teeth and jaws and increased likelihood for cavities.”
A “caries risk category” often determines how often dental X-rays are taken. The most recent documented resource to determine a caries risk is Caries Management by Risk Assessment (CAMBRA). This was adopted by the ADA and is used by dental professionals giving interval recommendations for X-rays.
Safety of Dental X-Rays
With knowledge of your risk for dental infection, you will be informed by the doctor of the interval at which dental X-rays should be taken. You can rest assured that the standards published by the ADA have been researched extensively and are there to protect your personal health and safety.
Dental X-rays are most commonly digital, which significantly reduces exposure. There is more radiation exposure from the sun or in an airplane than in a dental X-ray. It is common practice to use a lead apron with a thyroid collar for protection during X-ray exposure.
Having a cavity means having an active, potentially harmful infection. Diagnosing such infection with minimal exposure through digital dental X-rays at our Winchester, Virginia office does more good than harm.
