I just started using toothpaste with nano-Hydroxypatite after a recommendation from a friend. Obviously I can't say much about its effectiveness long-term. But it feels amazing. Feels like there's a protective layer over the enamel - hopefully there actually is! Apparently, nano-Hydroxypatite is even more effective than Novamin (which is still good): https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5121804/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5121804/ If you're in Australia and struggling to find toothpaste with Hydroxypatite, Chemist Warehouse stock "Healthy Care Sensitive Propolis Toothpaste". So far, highly recommended.
