Clean, unharmful ingredients.
Size: Pack of 1, 4 Ounce, Set name: A. Probiotic - Citrus Mint
Good stuff. I had somekind of an allergic reaction to a chemical in it, as I do most toothpaste though. Whatever it is, strips the lining of the inside of my mouth. It wasn't as bad as some of the other's that I have used though. I need to find out what it is in the toothpastes that I use that does this, so I can stay away from it. Otherwise, I liked the taste and how good it cleaned my teeth.

Fresh Taste and Super Clean Feeling
Size: Pack of 1, 4 Ounce, Set name: A. Probiotic - Citrus Mint, Size: Pack of 1, 4 Ounce, Set name: A. Probiotic - Citrus Mint
I’ve been using this toothpaste for a while now and just ordered my second tube. The citrus mint flavor is really — fresh but not overpowering. I also love that it’s safe for kids, so the whole family can use it. The fine particles leave my teeth feeling super clean and smooth, almost “squeaky clean” after brushing. It keeps my mouth feeling fresh for a long time and I’ve noticed much less plaque buildup throughout the day. Definitely one of the best fluoride-free toothpastes I’ve tried so far.

Love, love, love!
Size: Pack of 1, 4 Ounce, Set name: A. Probiotic - Citrus Mint
I love this toothpaste! It has done an amazing job removing plaque. It has helped my sensitivity immediately and I am able to handle cold water or drinks again without any pain. I also love that this is a prebiotic toothpaste.

Quality toothpaste with ingredients you can trust
Size: Pack of 1, 4 Ounce, Set name: B. Probiotic - Peppermint, Size: Pack of 1, 4 Ounce, Set name: B. Probiotic - Peppermint
Good toothpaste. It's a nice light scent/flavor. It's pleasant. My teeth feel fresh after using it. I'm excited to see the changes. I'll post a picture of my before and then I'll update in a few months of my after. I'm so grateful this is a natural product that focuses on replenishing rather than just scratching. I still wish it cost less, I mean 14 bucks for one toothpaste seems like a lot, but it's better than using toothpaste that's laced with poison so whatever. I hope one day they come down on their price. I like that the ingredients are quality.
