There’s something called… “Oil Pulling” to help clean teeth.
It’s an ancient practice. Usually it’s Olive Oil, but I’m sure any small-molecule oil would work. Fish oil is also a small-molecule oil.
You could probably use mineral oil as well. All equally small molecule. [I wouldn’t swallow the mineral oil necessarily but then again, if you’ve used it to clean your teeth, you probably want to spit ANY oil out anyway).
I’ve tried it before; might try it again.
Oh I have some article somewhere about tooth remineralization using breathing – lemme see if I can find it…
