It is trivial today to get whatever level of fluoride is recommended for dental health, via toothpaste. So there is no compelling need to fluoridate as there exist viable alternatives to achieve the same that fluoridation is for any other purpose than dental health.
In the USA, dental care is not covered by public insurance, and is an optional add-on to insurance through one’s employer.
So without addressing at all whether fluoridation is effective or safe, there doesn’t seem to be any compelling need to fluoridate public water, and there’s no economic down side for the public if governments choose not to do so.
Given this, why not just leave people alone to make their own choices? If the citizens in a city or state want to fluoridate the public water supply, then do so; if they choose not to, then leave them alone. It’s a free country and voters are grownups; let them choose for themselves.
If you live in a place that chooses the choice you dislike but for some reason fluoridated public water supply is a critical issue for you, either campaign to change it or vote with your feet.
This issue just doesn’t seem important enough to me to spend any effort arguing either way.
