You're the one who is incorrect here. We do, in fact, consume fluoride all the time in the food we eat and it has a role in bone and tooth health. The vast majority of people get more than enough in their regular diet (brewed tea has a fair amount) but there are probably extreme cases where a supplement might be required. Banning them is dumb and confidently posting about things you don't know for sure is worse.
Confidently posting links without reading or understanding them is worst of all. Your source does not remotely contradict my point. This says that, while we harmlessly consume incidental fluorine from the environment all the time, there is no recommended or minimum intake. That’s because it is not an essential nutrient. Its only use mentioned here is the prevention of dental caries, and then only when applied topically.
There is no such thing as “enough” consumed fluorine. Consuming fluorine bypasses your teeth, the only place it does any good. Enamel is not generated with fluorine in it; it must be applied afterward for anticavity benefits.
Do you have a credible source?
There appear to be multiple sources stating that mild fluorosis is associated with increased resistance to cavities, e.g. [0], which seems inconsistent with your statement.
