I saw a youtube video where someone said that Listerine "invented" the problem of bad breath just so they could sell their product, as if they're inventing problems that don't exist and then being "capitalist pigs", but bad breath smells disgusting. I'm glad we have oral hygiene products now.
Same with most beauty products
Well there were no doubt all kinds of people, some as clean as they could be, and some disgusting smelly and dirty, like there is still.
There's always been bad breath
You sure about that?
Yea people definitely ate mint leaves and other items in order to freshen their breath.
I think humans figured out that other humans could have bad breath ages before the toothbrush. There were probably many other "remedies" for it along with mint leaves.
But was it a common thing?
I'm pretty sure it was just a given back then.
