    haven't used enough to say

    I have only used this once so far and the flavor is okay. I prefer the flavor of the original better cause of its minty ness.

    Great alternative

    Great alternative to traditional toothpaste. Just the right amount of foam and minty fresh flavor. In fact I find that half a tablet is sufficient. I have sensitive teeth and this helps with that as well. Simple and effective ingredients. I do find them a bit pricy but I suppose you get what you pay for.

    The best toothpaste bites I've used

    Duo toothpaste bites are fabulous! They aren't powdery when you chew them like some are, and my teeth feel super clean and minty after I'm done. I'm going to keep buying them from now on.
