I remember back when I was in 5th grade and the dentist came in during a health class we were having where they gave us this red tablet you would chew on and it would show where you had junk on your teeth and where you needed to brush more. They gave fluoride toothpaste and a fluoridated mouth rinse. In 5th grade, you don't think your doctor/dentist would hurt you. Looking back now, I ask myself did these guys know about this and pushed it off on us, or were they misled too?
