You said they stopped it because there was no benefit. Do you have a source for that claim? Wikipedia (not a source) doesn't give reasons for the discontinuation of flouride.

Wikipedia does say that if you read further on, but unfortunately without primary sources. Unfortunately it's late here or I'd love to try and find some.

No, it's okay. You made claims which you then sourced to a Wikipedia article that doesn't say what you claimsd it said and doesn't contain references to what you claimed.

That tells me all I need to know.

Trouble reading much? http://en.wikipedia.org/w/index.php?title=Water_fluoridation...

Says exactly what I claimed. I'm not going to waste my time finding primary sources, because your asinine response tells me all I need to know.
