We've been putting fluoride in water for a long time, and there are multiple studies that have looking in to it, I don't know why you think there aren't?
But I prefer to rely on brushing my own teeth and avoiding certain foods to maintain my own health, rather than have a medication added to my water supply because the guy next door does not take care of his health.
So if you didn't have fluoridated water as a kid, having it as an adult still provides a benefit. This particular study doesn't say anything about having it as a kid and then stopping, but again, it's hard to find significant populations that have experienced that.
