Pineapple and papaya
Color: A - Magic Mint (Pack of 3), Color: A - Magic Mint (Pack of 3)
I like it okay. I will use all of it but I am unsure if I will buy it again. It foams very little. I feel like I use more than I do with other pastes/gels. My mouth feels clean without having that too minty/medicinal taste from traditional flouride pastes. It comes out of the tube easy and sticks to my brush. I didn’t know until after I purchased it that there is papaya and pineapple extracts. There IS a photo in the product description that says this and I neglected to click through them all. I have two members in my household that are allergic to those ingredients so I have not had them try it. The only taste is a mild mint though. I think the whitening effects of nanohydroxyapatite pastes is much better than other popular brands that boast “whitening.” My teeth simply look whiter and shiny.

And alternative to floride toothpaste.
Color: A - Magic Mint (Pack of 1)
I've been using this alternative toothpaste for a couple months now. It's expensive compared to regular toothpaste, but some suggest that it's healthier for your teeth. Nano hydroxyapatite is supposedly the same molecule that our teeth are made of. So perhaps it may be better for hardening teeth than fluoride. Of course, I can tell if it is doing that or not. Do your own research.
It's a bit more fluid than standard paste, so it sits more flat on the toothbrush. I've discovered that if it dribbles from your mouth onto your shirt, it leaves a white stain on the fabric! So don't use it while wearing your good work shirt. The taste is more mild than the usual minty toothpaste. Not bad at all. At my next dental exam we'll see if it's cleaning my teeth effectively.
