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.

GREAT CHOICE !!!

Color: A - Magic Mint (Pack of 1)

Definitely works as discribed helped with tooth sensitivity active ingredients help whiten and strengthen tooth enamel. I alternate 3 X a week woth normal Fluoride toothpastes and use this 2X a week. Total game changer
