    Surprisingly efficient

    These small tables leave your teeth super clean and I have noticed my teeth are whiter.

    Love this product!

    I love everything about this product starting with the little glass bottles. I've been trying to get rid of one- time use packaging for all my basic products like shampoos, laundry detergents etc. and the glass bottles along with the compostable refill pouches fit this goal perfectly. I've tried other tooth tablets before but I like the taste of these the best. They're minty but not overpowering. I've also been trying to pay attention to the ingredients in products and wanted to know more about the nano-hydroxyapatite in the product. I emailed the company and got a very detailed response from Mike, one of the co-founders of Duo. I will be a customer for life and am ordering starter sets for my grown children to get them started!

    Enjoying this but with bad breath mornings

    I think that maybe if you floss, then use mouthwash, then use Duo, then you won’t have bad breath in the morning. But if you forget the mouthwash, then Duo doesn’t seem to have a strong enough mint flavor to account for better breath in the morning. I didn’t have this issue with regular tooth paste. It’s just an adjustment though, because I love the toothpaste itself and do actually think that it has made my teeth whiter already after just one month of use. I love the way it makes my teeth feel. It’s like squeaky clean feeling. I’d recommend it!
