Published on Leave a comment on Some Dental Floss Brands Contain Harmful PFAS Chemicals

For a while now it has been known that some dental floss, such as Oral-B Glide, contain harmful chemical compounds called PFAS (per- and polyfluoroalkyl substances), similar to Teflon. These chemicals have all sorts of negative health effects, and are referred to as "forever chemicals" because they stick around.

A recent investigation by ehn.org (Environmental Health News) and Mamavation (a health/wellness site) tested 39 different brands of dental floss for PFAS by an EPA-certified laboratory. They found evidence of PFAS in one third of the samples, with levels ranging from 11 parts per million (ppm) to 248,900 ppm. Yup, it was Oral-B Glide with the incredibly high levels of PFAS.

These PFAS chemical compounds are linked to all sorts of health problems (e.g. kidney and testicular cancer, semen quality, thyroid disease, immune system effects, reproductive problems, and lowered sex and growth hormones in children) - so you want to avoid them if possible.

It turns out these chemicals are shed into the person's mouth when flossing if the floss contains PFAS, and can be measured in a person's blood.

The four floss brands with extremely high levels (over 70,000 ppm) were: Oral B Glide, Up & Up (Target brand) Smooth Slide Floss, Colgate Total Waxed Dental Floss, and Solimo (Amazon brand) Extra Comfort Dental Floss.

One piece of good news: No dental (tooth) floss marketed to children that they tested had indications of PFAS forever chemicals.

Bottom line: avoid non-stick smooth dental floss such as Oral-B Glide dental floss (or when the dental floss label brags that it is similar to Glide dental floss). Use plain waxed or unwaxed floss instead (e.g., Reach Waxed Floss, Tom's of Maine Floss). Look at the investigation results for brands to avoid and better choices.

That nice waxy glide as you floss your teeth? Turns out it could be courtesy of PFAS, the "forever chemicals" that hijacks hormones and is linked to reproductive problems, birth defects, testicular cancer and a host of other diseases.

Dental floss coated with a "non-stick coating" has long been a concern of mine. Do the Teflon-like chemicals get into the person when a person is flossing teeth?

These chemical compounds (called per- and polyfluoroalkyl substances or PFASs) are linked to health problems (e.g. kidney and testicular cancer, semen quality, thyroid disease, immune system effects, and lowered sex and growth hormones in children) - so you want to avoid them if possible. It turns out these chemicals are shed into the person's mouth when flossing and can be measured in a person's blood.

Bottom line: avoid non-stick smooth dental floss such as Oral-B Glide dental floss (or when the dental floss label brags that it is similar to Glide dental floss). Use plain waxed or unwaxed floss instead.

Per- and polyfluoroalkyl substances (PFASs) are a group of chemicals used in a wide variety of consumer products because they have water- and grease-resistant properties. They are used in nonstick cookware, in food packaging (especially the paper wrappers and cardboard containers) , stain-resistant carpets, furniture, floor waxes, textiles, water-proof and stain-resistant clothing (such as Gore-tex fabric), and performance gear.

How do they get into us? Some ways: the chemicals can migrate out of food packaging into food, or can be released into the air and dust from carpets and upholstery treated with stain-resistant coatings. PFASs have been detected in water, soil, and in the bodies of almost all Americans!

This study (and others)  found that higher levels of  these chemicals in the body occur with the following: frequent consumption of prepared food in coated cardboard containers, having stain-resistant carpets or furniture, using Oral-B Glide dental floss, and living in a city served by a PFAS-contaminated water supply.

It may not be possible to totally avoid all PFASs, but one can lower exposure to them (for example, don't have stain-resistant carpets in the house or apartment, and try to eat less fast-food).
