I asked my young dentist about flouride, as she has been in practice about 10 years, and I was sure she would have heard about the dangers of flouride. Nope, she said it's perfectly safe and keeps teeth strong. Told her I won't be using anything with flouride and she was fine with it. It's the same as when my dad was practicing years ago. I believe the dentist quoted there though, it is like the vax...people just go ahead with whatever they are told.
