Love this floss
Great non toxic floss. I love it. Much thicker than normal floss and so it’s more effective.

I really like this floss it fells like it does a better job at cleaning between teeth than the smooth plastic kind. The nano hydroxyapatite seems a nice bonus but not sure how well it works in floss

Works and EWG Verified!
I’m a big fan of David’s dental care products, as they are PFAS free, as well as EWG (Environmental WorkingGroup) verified. Floss works well, aside from occasional shredding.EWG VERIFIEDProducts that are free from EWG's chemicals of concern and meet our highest standards for health and transparency.

Great product!
This is my third order of this floss and I really like it. It doesn't seem to be waxed but still slides easily between my teeth and it doesn't shred or break.I also really like that I can use my original plastic case and buy refills, which make me feel good about not creating extra waste.

Cleans teeth well.
I love that I can buy this floss without the plastic case. The floss is terrific as well. The expandable floss does not get caught and tear in my teeth like others I have used. Really cleans in between the teeth.

It works!
Easy to wrap around fingers for flossing; it doesn’t slip off fingers.Very strong floss; can get a better glossing as a result.If you are looking for healthy alternatives to commercial floss, this is it. Try their toothpaste too!

Label
I do not see anything on this product’s label about being PFAS free, so I probably won’t but again unfortunately
