What this means for you

A Detox Score of 58 places pfas-coated dental floss in the Moderate band. The persistence rating is the standout concern here — these compounds linger in the body and environment for years. Some smooth 'glide' flosses are PTFE-based, and research has associated their use with higher PFAS levels. Plain waxed floss works just as well.
