Oral-B Glide floss linked to toxic PFAS chemicals, study finds

Patients who use Oral-B Glide dental floss may develop higher levels of per-and polyfluoroalkyl substances, USA Today reports.

Based on a peer-reviewed study published in the Journal of Exposure Science & Environment Epidemiology researchers found higher levels of perfluorohexanesulfonic acid, a PFAS, in women who used Oral-B Glide dental floss .

The study featured 178 middle-aged women to examine multigenerational impacts of environmental chemicals and other factors on disease. Oral-B Glide flosses were among the 18 floss products the study examined. Researchers tested the products for fluorine; and found six of the 18 products at flouring, an indicator of PFAS.

Floss and other hygiene products are listed as potentially containing PFAS by the CDC. Exposure to certain PFAS chemicals can lead to cancer, ulcerative colitis in adults and thyroid disease in children.

In a statement to USA Today, Oral-B said, "The safety of the people who use our products is our top priority. Our dental floss undergoes thorough safety testing and we stand behind the safety of all our products."
