I'm not saying you're wrong, but you made multiple strong claims without a single citation or study link. We could have a better conversation with data to look at. There's a decent (though somewhat biased) review of the debate in [1]. It's worth noting that if you read the linked studies there closely you'll find the truth is, as usual, nuanced. Specifically, that "fluoridation is a population-level caries preventive strategy" [which may or may not be effective at the individual or small community level due to other factors]. I.e., good at the national level for statistically significant reduction of tooth disease incidence, but at less-aggregated levels the confounding factors like diet and how often/well people brush their teeth are going to be bigger determinants of efficacy.
It's also worth nothing that 1) over-fluoridation is pretty bad and can affect poor or malnourished communities (ex, [2]); and 2) there are alternatives to fluoride that may be equally effective with fewer risks at higher concentrations (ex. nano hydroxyapatite).
