No, that is incorrect. PTFE is not a PFAS (it's chemically related, but is not the same).

You are perfectly fine with PTFE dental floss - it has no reactive PFAS components in it.

That is not a good recommendation and is also incorrect

PTFE, the material, does not contain PFAS in bulk form.

That's the end.

Floss, as a product, could contain any number of compounds related to the manufacturing, packaging and coating.

Interesting.

Take that with a grain of salt
