The people leading the health system are highly credentialed. Moreover, highly credentialed people, in medicine as in all fields, frequently disagree on what studies show, how valid a study is, what it's flaws and limits are, how conclusive it is, and so forth. And the consensus has a long, time honored tradition of being wrong from time to time.

Ultimately, the woo woo people are the ones who rely on someone in a labcoat to tell them whether ingesting government approved (there's your first red flag) synthetic fluoride from industrial byproducts is "necessary".

If it's useful, brushing it onto your teeth and into your gums 56,000 times in your life is probably sufficient, particularly given that we don't know with absolute certainty beyond any shadow of a doubt that the industrial waste options are totally without health consequences. I'll literally just take care of my teeth and cross my fingers over listening to modern medical consensus on a range of topics where I simply trust intuition and common sense more.
