PFJ 2021 ~ Try vegetable dental floss
Most dental floss sold in the USA is bad news for the planet in general (because it’s made from nylon and comes inside a #5 plastic box that isn’t collected for recycling in the vast majority of recycling programs) and for you in particular (because the string may be coated in PFAS, “forever chemicals” that are toxic and long lasting – and you are putting them in your mouth!).
Fortunately, there are more and more natural alternatives made from corn or bamboo fibers that come in refillable glass/metal containers. Or, if you have a horse, you can pluck a hair and try the oldest, most natural method to get food residue from between your teeth!
