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!

Apparently, nano-Hydroxypatite is even more effective than Novamin (which is still good): 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.

Totally agree! The brands I use are - Apagard - Boka - CTx4

Another interesting teeth restoring substance I just discovered:

Oligopeptide P11-4 [1]

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.

I ordered some from Canada, made in Canada, using Ebay (about as reliable as Amazon but it doesn't come from India and it is cheaper).

I went looking on Ebay but couldn't find anything in Canada, do you mind sharing the brand or keyword?

Sorry I was talking about the Novamin one... I think the nano-hydroxyapatite one is available in the US.

Have you checked out Biomin? It’s meant to be an improved version of Novamin.

I have never heard of this Novamin toothpaste before. Nor has any of my dentists ever recommended it.

It looks like the popular brand is Sensodyne.

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).

Article from 2018 about that:

"As of the time of this update, Sensodyne toothpaste with NovaMin is now available on Amazon to buyers in the USA, directly from Sensodyne/GSK."

That article really helped me understand what this is all about, ty!

Quick googling found a funny metastudy: "The articles from the database obtained for further review was N = 1. According to the study..."

Haha, I read the same after googling.

I never heard of Novamin, but I used Sensodyne for years becase it tastes better.

Has it helped with maintaining the health of your teeth?
