What do you mean, "take fluoride?" I only know of it being in Florida well water or toothpaste.
There's lots of evidence that it does reduce cavities. Lots. When scientists noticed that many people in central Florida had great teeth, no cavities, that's what they determined.
I'm not saying you should be forced to consume it, but OTOH, there's nothing bad about it. When the public water systems started adding it in the sixties we were told it was a Communist plot. Yawn.
But congrats on a good exam.
