It's not only FDA approved but required, because it's good for your teeth and shit. We all know that the government cares about our well being. Who cares if the pineal gland in our brains get all clogged up with calcium so we'll be more complicit with what the TV man says? What's important is we all have healthy teeth. We know fluoride is good for our teeth because the TV man told us it is. I'm going to go open a cool and refreshing can of soda with FDA approved fluoride and FDA approved HFCS while watching TV to get my daily dose of how diversity is our strength right now.
