Somebody is getting paid for that fluoride.
A long time ago, it was decided US fluoridation "improved public health" with the quick win of moving the needle of tooth decay while failing to consider the long-term, detrimental health effects of systemic fluoride ingestion. The rest of the world doesn't do it because of the evidence against it and widespread availability of modern dental care products containing fluoride.
The trivialization of anti-fluoridation is primarily due to mass media indoctrination, i.e., Dr. Strangelove, and association with conspiracy wingnuts.

Much of continental Europe does fluoridation through dietary additions (e.g. salt). Just because it isn’t in the water doesn’t mean it isn’t added. There are some countries that notably don’t fluoridate at all, and many fall into two camps: they either don’t have safe municipal water supplies, or already have naturally high fluoride levels (sometimes higher than the US’s introduced levels).
You’ve flipped the causality, by the way: it’s in Dr. Strangelove because it is a conspiracy wingnut thing to obsess over.
Second: if you think that the average American will remember the ADA for fluoride, I'll ask you for your opinion on General Motors. They actually did poison our air and soil with a known neurotoxin for over 50 years, and they seem to be doing fine in the court of public opinion.
