Preventing cavities is far more effective with topical application of fluoride on the teeth, rather than ingestion.
I personally don’t buy the passive health benefit. Even if it’s true, there’s no proof that fluoridated water is superior to topical application.
Not to mention that if we’re going to just roll over and accept stuff in the water for public health reasons, what really should be added are more vitamins, not fluoride. In particular vitamin D
For children developing their “adult teeth” fluoride ingestion strengthens those teeth before they pop out. Topical has no effect obviously since they haven’t surfaced yet.
And for that there is fluoride mouthwash, which again isn’t ingested and would be more effective.

That doesn’t work because it’s topical. You give kids vitamins to get fluoride into their system to strengthen their developing adult teeth.
