Works and tastes good too.
I've tried several different brands of nano hydroxyapatite toothpaste. This is the first one that makes my teeth look brighter and feel healthier. My husband likes it too.

Good Stuff!
Flavor Name: Mint, Size: Pack of 1 (4 Ounce)
I have been trying different non fluoride toothpaste and I think I have found a winner! This toothpaste leaves my teeth clean and my mouth fresh! The texture is great and I am impressed with the ingredients. The price is a little pricey but you only need a pea size amount. Very easy to use and does not run out of the tube like some non fluorides Ive used. Definitely will buy again!

Flavor Name: Mint, Size: Pack of 1 (4 Ounce)
I love this toothpaste! I have tried several hydroxyappetite pastes and this is by far my favorite. My teeth feel clean, I have zero sensitivity issues anymore and my dental check ups are very good.
