Not enough of us floss regularly, and even fewer think about what’s in our floss, but maybe we should.
NBC 5 Responds uncovered surprising and potentially dangerous chemicals hidden in some of the most popular dental floss brands.
Dentists say flossing makes a huge difference – and that’s not changing.
But the results of a new Consumer Reports analysis of what’s in your dental floss might make you think twice about the type of floss you use.
“Some flossers contain PFAS chemicals for a smoother glide,” said Catherine Roberts of Consumer Reports. “However, these ‘forever chemicals’ have been linked to various health problems and environmental concerns. Some flossers also contain undisclosed flavors and are made of plastic.”
Consumer Reports and MADE SAFE, a nonprofit organization focused on product safety and sustainability, recently analyzed the ingredients in a variety of dental floss products.
Ten dental floss products did not disclose their ingredients, contained PFAS, or included other components linked to health concerns, posing higher risks to consumers.
Three dental floss products stood out as favorites because they contain safer and longer-lasting ingredients.
While companies are not required to disclose all dental floss ingredients, Tom’s of Maine, Dental Lace, Cocofloss and Nudge provided Consumer Reports with full ingredient lists and confirmed that they do not intentionally add PFAS to their products.
Procter & Gamble, maker of Oral-B Glide dental floss, has confirmed that its floss contains PTFE, a type of PFAS, citing its performance benefits. However, they maintain that it is safe and free of some PFAS that are being phased out.
Humble Co. provided partial information confirming PFAS-free status, but provided incomplete details on flavors.
The other companies did not respond to Consumer Reports’ requests for comment or questions.
For people who hate flossing, how about a water flosser?
“Water flossers, like Waterpik, are effective at removing food debris,” Roberts said. “And while they’re not as effective as floss at removing bacteria, they’re a great option for people who don’t like flossing or have trouble using it.”
Remember, the best flossing method is the one you will use regularly.
Consumer Reports recommends choosing dental floss coated with natural substances like beeswax or vegetable waxes and looking for dental floss made from biodegradable materials like silk or cotton and either unflavored or flavored using disclosed natural ingredients.
