Good but not great
This tooth paste tastes very good but I'm not sure it has enough grit to keep teeth clean. My kids have to brush at least 3 times a day to keep their teeth white and not yellow. I help them brush at least once a day and we have had good check ups while using Boka

Love it !
Size: 4 Fl Oz (Pack of 1), Set name: A. Charcoal Yuzu Mint
I ordered Boka Fluoride-Free Toothpaste because I wanted a natural alternative without fluoride. It has a pleasant, mild mint flavor that isn’t overpowering, though I have to say it has a slight taste that reminds me of a banana peel kind of unique but not unpleasant. The toothpaste has a smooth texture and cleans well without being harsh or drying.
After using it for a few weeks, I’ve noticed my teeth feel fresh and my gums aren’t irritated at all. It’s a great option if you’re looking for a fluoride-free toothpaste that still gives you a clean, fresh mouth.
I’m happy with this product and plan to keep using it.

Kid and mom and dental professional approves. P.S get the floss too.
My toddler loves this toothpaste. He gets so excited when he sees me load up his toothbrush for the evening. I like that it is fluoride free so I don’t have to worry about him eating it. Because he will, because he is 16 months old. I love that it still has the remineralizing component (anti-cavity, strong enamel) of the nano-hydroxyapatite. As a dental hygienist (and mom) this is important to me.
Personally… the vanilla cardamom is not my favorite flavor. I wanted to try out the limited edition and I like cardamom (just not in toothpaste apparently) However, my son loves it! Boka has lots of different flavors I’m sure we will try over time. I’m sure I will find one I like better.
P.S Boka floss is amazing. I recommend it to many of my patients, and I use it at home.

Torn About Whether to Keep Using
I bought the Vanilla Cardamon flavor, because I'm allergic to mint, and it makes my mouth swell. It tastes nice. The "flavor" doesn't last a long time, so you don't necessarily get that fresh breath feeling. The toothpaste works fine. There seems to be some controversy over whether Nano Hydroxyapatite Toothpaste really protects teeth as well as fluoride, but I know some people swear by it. Obviously, there is also lot of controversy regarding fluoride and whether it's healthy, so I get why this might be a better option for some. I've been using it for about a year, and I got a fairly bad cavity recently, but of course, this is just anecdotal evidence. I'm not sure whether I'll keep using it or not.

Great for sensitive teeth
Size: Pack of 3, 4 Ounce, Set name: E. Ela Mint, Coco Ginger, Lemon Lavender
If you have sensitive teeth, these are great. I had prescription toothpaste and couldn’t get it anymore and picked this up. It’s helped tremendously. No different than normal toothpaste consistency-wise but the flavors are the best.
