There are lots of "big deals" in the environment that we silently tolerate -- things which studies conclusively and repeatedly show are substantially detrimental: * Roadside air pollution * Lead pipes * Indoor CO2 buildup Studies relating to flouride are nowhere near as conclusive and show nowhere near the same magnitude of effect. If flouride is contributing negatively in a similar way, it's doing so to such a small extent that it very nearly falls within the margin of error. Anyone genuinely worried about flouride should consider double-checking that they've already taken more meaningful action regarding their health, such as going on a walk, getting a full night's rest, or opening a window.
