If I don't floss my breath stinks. So I floss.

The thing I wonder about is the "wax" on waxed floss. Am I shredding PFAS (forever-chemicals) all over my mouth?

Waxed dental floss seems like the exact use case for PFAS - making something non-stick/slippery.

And...after searching instead of wondering - yes some flosses contain PFAS. https://www.buzzfeednews.com/article/nidhisubbaraman/oral-b-...

How do you know your breath stinks? Isn't that really hard to detect on yourself?

Take a metal teaspoon, scrape your tongue, and sniff it.

Look in the mirror, and if the back of your tongue is white or white-ish at all, your breath stinks. That white stuff is bacteria.

Did not realize this until my 20s. Most people don't tell you when your breath smells bad.

But does your breath stink? There will always be bacteria in your mouth. Doesnt mean it will always stink.

Well you can easily try it. Scrape a chunk of the white off the back of your tongue, and smush it between tour fingers. Does it stink?
