That's nice, but fluoride does not improve oral health; it just replaces calcium .

Isn't that like saying steel armor doesn't improve ship battle resilience, it just replaces wood? There are multiple aspects of oral health that it might not help, but it can e.g. help prevent cavities and infections from them.

It replaces hydroxide ions between phosphates in the calcium hydroxyapatite crystal structure of the enamel. This reduces the loss of calcium due to the mild solubility of the mineral and neutralization reaction of the hydroxide with acids.
