Dental Flossing, Other Behaviors Linked with Higher Levels of PFAS in Body

A new study suggests certain types of consumer behaviors, including flossing with Oral-B Glide dental floss, contribute to elevated levels in the body of toxic PFAS chemicals. PFAS are water- and grease-proof substances that have been linked with numerous health problems. The findings provide new insight into how these chemicals end up in people’s bodies and how consumers can limit their exposures by modifying their behavior.

The study, led by Silent Spring Institute in collaboration with the Public Health Institute in Berkeley, CA, appears online January 8 in the Journal of Exposure Science & Environmental Epidemiology (JESEE), and is part of a special issue dedicated to PFAS (per- and polyfluoroalkyl substances).

PFAS are used in a range of consumer products, including fast food packaging, non-stick pans, waterproof clothing, and stain-resistant carpets. People can be exposed to the substances directly through the products they use and the food they eat. They can also be exposed through indoor air and dust and contaminated drinking water.

Scientists are concerned about widespread exposure to PFAS in the population because the chemicals have been linked with health effects including kidney and testicular cancer, thyroid disease, high cholesterol, low birth weight, decreased fertility, and effects on the immune system.
