Some Dishonest Dentists Promoting Fluoride in The Water !!!

As far as dentistry goes, there's enough fluoride in the toothpaste and mouthwash to keep our teeth in good shape. What is the need to force millions to ingest it? How does drinking it help your teeth besides the brief moment it passes by them? It seems ridiculous to me.Fluoride acts topically. Fact. Would you drink suntan lotion? No, you would not. So why would you drink fluoride? These kids are eating crappy food and not brushing their teeth. Besides It isn't even fluoride they put in tap water, It's hexafluorosilicic acid... An acid so aggressive it can dissolve glass, if anything it's worse than fluoride - which btw is an inorganic compound... fluorine the element is very, very scarce in nature.
