Drops are easier to open
I like the zolli drops better than the pops. They are easier to open!

Great option for fluoride-free families, has helped my sensitive teeth dramatically
This is a great non-fluoride toothpaste. Our whole family switched to nano hydroxyapatite instead of fluoride pastes, we have had great dental visits and no regrets. No one has had a cavity since switching 2 years ago, but three of the four of us didn’t have cavities to begin with. I would say that my own sensitivity to cold (something I’ve had for 40 years) has decreased significantly since using this daily. This paste is far more effective for sensitivity than high fluoride options have been for me. My two teenage boys both love this toothpaste. My teeth feel clean. I wouldn’t say the toothpaste whitens better than any other paste does. My mouth feels fresh after brushing. I like the idea of remineralizing tooth surfaces but I don’t know how I would quantify that. The flavors are all good, I would rank them as follows: lemon lavender, mint, cinnamon mint, cardamom, ginger (don’t get it if you don’t LOVE ginger). Cardamom is really nice but I could see getting tired of it. Ginger is kinda weird. My boys love the lemon lavender the best. The flavors can be intense but in a natural, not artificial way. It’s not too sweet at all like some pastes can be. This toothpaste is absolutely worth the higher price point. I feel good about my family using it.

Lovely
Size: 4 Fl Oz (Pack of 1), Set name: A. Charcoal Yuzu Mint
Not one of the best flavors out there. I'm not used to charcoal. The flavor and texture is a bit off for me, makes me gag every-time but it is One of my favorite toothpastes after transition from sensodyne & proenamel. I never thought I would be able to go to a different toothpaste with my teeth being insanely sensitive. After doing some research and a family never recommend the brand boka I decided to give it a try. Let me tell you that my teeth have never felt better with the sensitivity and cleanness. It freshened your breather well and all the ingredients are so clean and good. I love that I can even give it to my toddler and not worry about her swallowing to much. Give this toothpaste a go!!!! The flavors are amazing. We have definitely tried almost all, we do end up going back to this one and the whitening one.

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
