When comparing hydroxyapatite (in nano or micron particles), it consistently performs equally well or better than fluoride. It’s been the go-to option in Japan over fluoride toothpastes for over 40 years over sodium fluoride.

flouride for teeth is fake science. Just rinse after food, especially after sweets, bread and pastry
