Study finds dental X-rays linked to tumor risk

Frequency pivotal, new study shows

Frequent dental X-rays are associated with an increased risk of developing the most common, noncancerous brain tumors, according to a new study, a finding that researchers say should serve as a reminder that even dental X-rays may be harmful if ordered too often.

Far from suggesting that people should skip dental X-rays, the researchers said that the new information should become part of the conversation people have with their dentists, especially since the American Dental Association’s guidelines suggest that healthy patients without cavities and free of risk factors should get bitewing X-rays once every one to three years, depending on their age.
