This is such a weird way of looking at it.
Imagine, for simplicity, there's an optimal amount of fluoride to add, which is X. Also imagine science can guess the number but, obviously, it's not perfect.
What will happen is that we will start at some number, and gradually change it as we get more knowledge. Sometimes we'll be below X, sometimes we'll be above X. When we're above X, and we find it out, we'll say "Oops it was too much fluoride, let's reduce it a bit."
And obviously policymakers need to work on imperfect information, so sometimes we have to add Y amount of fluoride even though we know it's not optimal - because, the alternative, adding zero fluoride, would be actually worse.
This is totally natural way of how science works, and saying that this undermines public trust of science is actually a point in support of GP, namely, the American public has poor understanding of how science works, due to poor education.
