hmm....yea i know that fluoride bi-products from natural gas harvesting plants is considered so toxic that it is actually kept on vacumed chambers, and yes, i have read the warnings, and i agree it does nothing for you. unfortunatly for me i have to use sensitive toothpaste which means the fluoride level is bumped up to counter the extra strontium acetate and potassium nitrate levels, because "sensitive teeth need extra protection!" I think its the strontium acetate/potassium nitrate that does any good, not the fluoride....YUCK
