Every single day we use a ton of different products. Some products are essential and obvious, like our phones, but others are so routine that we barely even consider them.

However, it might be time to consider all of the little things in our life, because some of them could be affecting our health — even something as minuscule and seemingly unimportant as the floss we use.

PFAS, often referred to as "forever" chemicals, have been detected in various dental flosses on the market. So, we've rounded up some PFAS-free dental floss brands to check out.

Nonprofit publication Environmental Health News teamed up with wellness site Mamavation to investigate the presence of PFAS in everyday products in September 2022. The study revealed that these toxic substances are common in various dental floss brands, with the highest levels in Oral-B Glide.

The research also found organic fluorine, an indicator of PFAS, in Up & Up Smooth Slide Floss Mint, Colgate Total Mint Waxed Dental Floss, and Solimo Extra Comfort Mint Dental Floss, as noted by Mamavation.

Previous research from 2019 had also uncovered a link between Oral-B Glide floss and PFAS, according to Harvard’s School of Public Health. The study found that those who used Oral-B Glide floss had higher levels of a certain type of PFAS in their blood than those who didn’t.

Finding these chemicals in a daily-use product can be a bit alarming. PFAS have been linked to developmental issues, a weakened immune system, liver damage, heart disease, and cancer — so it’s not exactly something we want to find in our floss.
