A family of toxic chemicals called PFAS is commercially used as flame retardants to make Teflon-like coatings. Among the adverse health effects of PFAS are cancer, immune toxicity, thyroid disease, and reproductive effects.





In a study, the six dental flosses were tested positive for PFAS:

· CVS Health Ease Between Super Slip Dental Floss Waxed

· Oral-B Glide Pro-Health Mint

· Glide Pro-Health Original

· Crest Glide Deep Clean Cool Mint Floss

· Safeway Signature Care Mint Waxed Comfort Floss

· Colgate Total Dental Floss Mint

According to a study by the Silent Spring Institute in Newton, Massachusetts, and Berkley, California-based Public Health Institute, “Using dental floss containing PFAS is associated with a higher body burden of these toxic chemicals.”

PFAS or per- and polyfluoroalkyl substances is a family of thousands of chemicals that industry prizes for their anti-grease, firefighting, and waterproofing properties. They are used in everything from pizza cartons, microwave popcorn packaging, stain-proof carpeting, water-resistant clothing, cookware, and even, apparently, unknown to much of the public until now, dental floss.

Oral-B Glide flosses were among the 18 floss products studied, say the study authors in the Journal of Exposure Science & Environmental Epidemiology. Scientists said they tested the various products for fluorine, an indicator of the PFAS polytetrafluoroethylene, or PTFE. Six of the products had fluorine, including the Oral-B Glide product,s and others marked with "compare to Oral-B Glide."

Product testing confirmed that Oral-B Glide and competitor flosses contained detectable fluorine, said the study authors. Between high blood levels and the confirmation of testing, “these results strengthen the evidence for exposure to PFASs from food packaging and implicate exposure from polytetrafluoroethylene (PTFE)-based dental floss for the first time.”

Responding to an article in USA TODAY, Oral-B said their own didn’t find any of the substances in the study. “All three Glide products that we tested contained fluorine, consistent with available information that Oral-B Glide is made with PTFE and supporting our hypothesis that Oral-B Glide is a potential exposure source for PFAS.”

“The good news is, based on our findings, consumers can choose flosses that don’t contain PFAS,” Boronow said.

PFAS-free dental floss that use silk or nylon, which are least likely to contain PFAS chemicals, and are wildly available.
