Activated Charcoal Floss

Does your floss contain potentially toxic PTFE or PFAS chemicals?

No, neither DrTung's Smart Floss nor our Activated Charcoal Floss are made from PTFE, the floss material implicated by USA Today as being potentially toxic. Instead, Smart Floss is made from polyester fiber and patented for better cleaning. PTFE material, although used widely for floss because it slides up and down easily between teeth, is in fact also the worst performing floss as far as plaque removal goes. (See the pic showing our study comparing Smart Floss to PTFE (like Glide) and other flosses, in the description tab of Smart Floss).
