Comment on flouride
Umbrias@beehaw.org 4 weeks agoyes fluoride diffuses into enamel and chemically and mechanically hardens it. this effect is strongly linked to better dental outcomes for children and adults. also, tons of blaces actually remove fluoride to the needed levels because it is naturally higher.

That’s good. My first instinct would’ve been that what’s in toothpaste is plenty.

nah it’s actually pretty low, toothpaste isnt in your mouth for a huge amount of time and it needs to be a certain level of nontoxic for edibility. this is why dentists still do fluoride soaks. the fluoride in the water also accumulates in and hardens bones a bit, though not a ton.
