I've used PTFE dental floss for decades, and recently diagnosed with a thyroid condition. I wonder if there could be a connection. This test will at least give me an idea of my blood levels of PFAS.



Honestly, the dental floss is the most fucked PFAS application out of all of them.


What floss should one use to avoid these chemicals?


There's no PFAS labeling requirements and i bet a lot of the manufacturers lie anyways. I have no idea.

I went with Grin because they said it's PFAS free. Best I could do.


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
