What it fails to prove -- or even correlate -- is that added fluoride in water and/or table salt has a strong enough negative effect to make it not worthwhile to add.
Despite the universally diminished cases of tooth decay, the presence of fluoride in water and/or table salt is nevertheless beneficial. Even if only 10% beneficial, it is still beneficial.
It's like refusing to take Penicillin because it too is bacteria!
