Novamin toothpaste has been life changing for me. Cannot recommend highly enough. A tooth that was deteriorating and the dentist wanted to cap is now fine enough for them to simply keep an eye on.
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!
If you're in Australia and struggling to find toothpaste with Hydroxypatite, Chemist Warehouse stock "Healthy Care Sensitive Propolis Toothpaste". So far, highly recommended.
I’ve had similar success with toothpastes containing “nano-hydroxyapatite” Amazon has several good ones.
I also have 2 kids, the youngest (4 yr old) had cavity issues which required intervention and then we started using the hydroxyapatite toothpaste and had no issues since.
I also headed down this path via looking for Novamin. I wish there was a reliable way to get it without the “is it fake” on Amazon. I’d gladly accept any reliable sources.
Sensodyne does not have Novamin in the USA(insert conspiracy theory here). You'd either have to import it from a reputable supplier, or try an alternative like Apagard or Biomin F(both of those have to be imported too, but are more readily available).
