Favorite toothpaste! Love the Ginger Flavor
This is my favorite toothpaste! I have very sensitive teeth and this has improved that sensitivity quite a bit. I like that Boka offers many different flavors that aren't typical "kid flavors." I know some folks, especially neurodiverse, are averse to mint and the ginger is nice and refreshing without being overpowering. Nano toothpaste is easy to use, doesn't require water even, and is a nice consistency like a gel. No gritty feeling like with typical toothpaste. My dentist was please with my teeth last time I visited after using for 6 months, so it's doing what it's supposed to do.

Good toothpaste, some flavors not so good
Cleans fine but I really do not like the cocoa ginger flavor. Lemon lavender is really good.

Tasty!
Flavor Name: Chocolate Caramel, Size: 5 Ounces
I didn’t miss the sugar at all. Can’t even tell that it’s sugar-free. The taste and texture are just like sugary caramels.
