> Other products have popped up such as BioMin, a toothpaste that contains Fluorocalcium Phosphosilicate. But again, this is another toothpaste that is not available in the United States.
I haven't had any trouble getting SensoDyne Novamin in the UK or Australia. Funny, usually it's the US that has the more lax regulations, not the other way round.
Regarding the benefits the author mentions: you can just buy toothpaste with actual nanohydroxyapatite in it. I currently use the David’s brand off of Amazon and I like it.
