My dentist in Clark County, Arkansas had a sign above the door going out of the waiting room to the treatment rooms that said, to the effect, "Fluoride is Poison." He also featured non-fluoride toothpastes and an oxygenating water machine for use to all at the counter where one pays the bill. Nothing hidden.

Nobody had to ask him. He put it all out there. You're either showing it or blowing it.
