First, fluorosis isn't demineralization of teeth, it's hypermineralization, way on the other side of the spectrum.
Second, you'll get water poisoning before you'd get fluorosis from tap water. I challenge you to find anyone who has gotten fluorosis from tap water alone
So long as the tap water is correctly treated, it's not going to give you fluorosis, but in the event the plant breaks and no one is testing the water, it can happen
