    Tooth whitener
    Flavor Name: A Coconut+Green Tea+Peach
    I have used the green bottle so far! As soon as you bite into one, it starts to foam up. I let it foam for a few minutes, and then I brush my teeth. It does freshen your breath and I think it's making my teeth whiter! I have not had a chance to try the other flavors yet. The flavor is mild but good! It is fun to use!

    Flavor Name: A Coconut+Green Tea+Peach
    These are very interesting. They work very fast like they said. The taste isnt bad so far ive tried the peach and its nice and strong. Only thing id say is its not like brushing your teeth like it claims its more of like a stronger breath mint that foams. Other than that id say its a great mint and product as a mint that you need to spit out haha. I look forward to using them.

    Don’t waste your money.
    These are horrible tasting …not even able to keep it in my mouth. Four people, including myself, tried them and everyone spit it out immediately. Don’t waste your money.

    Wow. Explosion of froth and mouthwash in one little tablet.
    Flavor Name: 2-Bottle Green Tea
    I love these for travel, and put some in a tiny container in my purse, too. You just have to spit it out - no rinse necessary. I might try a different flavor than the green tea. Don't love it, but do love the product.
