As a young dentist many moons ago,I visited and treated some aboriginal communities in the Great Sandy Desert,where their drinking water was very high in natural fluorides:most had black/brown flourosis affecting most of their teeth.Didn't see any old ppl bending over with osteoporosis.If fluoride was bad for their general health,how come they survived out there and bred for millenniums?I supposed they drank water in moderation,eh? Lol,it was very hot out that way too!
