Published on Tuesday in the Journal of Exposure Science & Environmental Epidemiology, the study found that “women who said they flossed with Oral-B Glide floss had higher levels of a PFAS called perfluorohexane sulfonic acid (PFHxS) in their blood than those who didn’t.”1 (Studies in people have linked PFHxS to liver damage and a decreased immune response.) The survey included 178 women, 87 of whom were black and 91 who were non-Hispanic whites. Katie Boronow, a staff scientist at the Silent Spring Institute in Newton, Massachusetts, who was part of the study, insists this is not about fear or encouraging people to stop flossing. Rather, it’s about choosing – and demanding (in my opinion) – safer products. Scientists have apparently known for a while that PFAS are used in Glide but these findings suppest that this is a much more important issue: “In addition to looking at the women’s blood levels, the researchers analyzed the chemical makeup of 18 types of dental floss. Six tested positive for fluorine, an element that they said indicates the presence of PFAS compounds.
