PFAS in dental floss:

Not bashing the conclusion, but I seriously thought it was common knowledge that Oral B glide and equivalent products were PTFE based.

It’s also annoying that people lump PTFE with other PFAS when it is pretty clearly less of an issue (note: not completely trouble free) in most cases.

‘Common’? I suspect a sampling of random people on the street would approximate closer to zero

It used to be a big selling point of Glide that it's made with Teflon/Gore-Tex: it was originally made by Gore and had the Gore logo right on the package.

Nope. I bought it because I absolutely hate flossing, and I absolutely need to floss, so I bought Oral B Glide as an effort to get myself to floss.

Lumping PTFE with PFAS is willfully misleading people.

The two might have things in common during manufacturing, but as a final product delivered to a consumer? Utterly different.

PFAS in many things you use every day:

I’ve switched to using Radius silk floss - it’s better in almost every way compared to the various brands we’ve tried. Only annoying thing is the packaging but it’s plastic free also.

Yea silk floss is really nice. Food caught between your teeth sticks better to the silk than to glide, and getting the silk between your teeth requires slightly more pressure, which feels nice to me.

The glide actually cause problems with shoved food into my gums that only the dentist was able to remove later.

It’s amazing when you look at this measure it says that Glide has 240k ppm (24% of entire product mass) was organic flourine!!

Yah that link is a lie, and I quote: "It’s important to note that our lab is not looking for PFAS compounds directly, because it’s simply impossible to look for all of them."

"levels of organic fluorine, a marker for PFAS" - yah, that's basically an outright lie. Flourine is also a marker for Teflon (PTFE) which is 100% not a problem.

This is junk science taken to it's ultimate level.

Dr Tung FTW!

What do you mean? Dr Tung's is listed under '“Not Our Favorite” Tooth Floss Brands' and considered to contain PFAS (although there appears to be some dispute in the comments).

wait what? what article are you reading? DR Tungs site says "All our floss is free of PTFE and PFAS (polyfluoroalkyl substances)."

What on earth are you smoking, that is NOT the actual link. That is some woo-woo garbage page. Please check this thread again.

The actual FA:

And the OP:

https://cen.acs.org/environment/persistent-pollutants/Fast-f...

If you look at the actual FA, it cites the article from mamavation. That is literally the first link, in the FA.

I think I'm the FA. And I don't mean F**ing article.
