Your Dental Floss May Contain Toxic Chemicals, Study Finds

Dental floss which contains PFAS (per- and polyfluoroalkyl substances), is linked with a higher body load of toxic chemicals, according to the Journal of Exposure Science and Environmental Epidemiology.

According to the study lead by US-based Silent Spring Institute, dental floss could contribute to high levels of toxic chemicals that can lead to health complications, especially in women. Such health problems may include high cholesterol, kidney cancer, low birth weight, and testicular cancer among others.

The researchers measured the presence of 11 different PFAS, water- and grease-proof substances, in blood samples of 178 middle-aged women. The results indicated that women who flossed with Oral-B Glide appeared to have higher levels of a type of PFAS called PFHxS (perfluorohexanesulfonic acid) in their body compared with those who did not.

Lead author Katie Boronow, a scientist at the institute said;

 “This is the first study to show that using dental floss containing PFAS is associated with a higher body burden of these toxic chemicals. The good news is, based on our outcomes, consumers can choose flosses that don’t contain PFAS,” she stated.

The team also tested 18 dental flosses, including three Glide products, for the presence of fluorine — a marker of PFAS, all of which tested positive for fluorine. The new discoveries are consistent with earlier reports which stipulated that Glide is manufactured using Teflon-like compounds.

The researchers established that women who frequently ate prepared food in coated cardboard containers, such as French fries or takeout, had high blood levels of PFAS chemicals.

Borownow further added;

“Generally, this study strengthens the evidence that consumer products are an important source of PFAS exposure. Restricting these chemicals from products should be considered a priority to cut down the levels in people’s bodies.”

Other deeds that were associated with higher PFAS levels included having a carpet or furniture that is stain-resistant and living in a city served by a PFAS-contaminated drinking water supply.

The study was published in Journal of Exposure Science and Environmental Epidemiology (JESEE).
