I use apagard premio, came across it while doing research a couple of years ago (4-5) on nano hydroxyapatite. I've never really had problems with my adult teeth and I continue to not have problems, so at the very least, in my case, is not any worse than fluoride toothpaste. My dentist loves my teeth :D she told me whatever I'm doing, don't change a single thing.
