I'm no fan of mass medication without a choice (or supplementation, whatever), but what you state is not the full story:
> They don't have it in Europe and have dental health that's just fine.
Much of Europe (not all) doesn't fluoridate their water, but they DO fluoridate salt and milk, or have high levels of natural fluoride in their water.
To quote wikipedia[1] (yes, yes, I know, although they at least have a citation[2] for it):
> the European Commission finds no advantage to water fluoridation compared with topical use
> Community water fluoridation is rare in Continental Europe with 97–98% choosing not to fluoridate drinking water. Fluoridated salt and milk is promoted in some European countries instead. Water fluoridation has been replaced by other modes in many countries where water supplies are too decentralized for it to be a practical choice, or existing natural fluoride levels were already ample, including Germany, Finland, Japan, Netherlands, Sweden, Switzerland, Denmark and at a time Israel.
That doesn't mean they didn't find fluoridation useful, just that topical use is just as good.
Personally, I dislike the idea of forcing everyone to use fluoridated products (by not providing alternatives, or by putting it in all the water) and would prefer if topical use were encouraged instead, but my preferences aside, fluoride has been proven to be beneficial to teeth.
