New ADA Recommendations on Dental X-Ray Safety

The American Dental Association recently updated its recommendations regarding dental radiography safety. One of the most notable changes is that lead aprons and thyroid collars are no longer routinely recommended for dental X-rays when modern equipment and proper imaging techniques are used.

Current evidence shows that these protective barriers are not necessary for routine dental radiographs. In some situations, lead aprons or thyroid collars may interfere with image quality and require the X-ray to be retaken, which can increase unnecessary exposure.

The updated recommendations continue to emphasize radiation safety. Dental X-rays should be taken only when they are clinically necessary and should be based on each patient’s individual needs, including symptoms, dental history, cavity risk, gum health, and planned treatment.

Dental radiographs remain an important diagnostic tool. They allow dentists to detect concerns that may not be visible during a clinical exam, such as cavities between teeth, bone loss, infections, impacted teeth, etc.

The new recommendations reflect a continued effort to use imaging more precisely and responsibly. Modern dental X-ray technology uses very low levels of radiation, especially with digital imaging, and the goal is always to obtain the necessary diagnostic information with the lowest reasonable exposure.
