Working really well so far! Equal if not better than Sensodyne
Size: Pack of 1, 4 Ounce, Set name: A. Probiotic - Citrus Mint
Love this toothpaste!! Ive been using Sensodyne for a while because I have had lots of cavities and such sensitivity. Ive gotta say this is equal to if not befter then Sensodyne! Its DEFINITELY helped my teeth sensitivity and it whitened them!! I will continue this and hope it keeps working and prevents future cavities. This flavor is also awesome.

Love it BUT it MAY cause dry mouth?
Size: Pack of 1, 4 Ounce, Set name: B. Probiotic - Peppermint
I love the mild minty flavor and the fact it is probiotic. I have been using Boka flouride free Nana-Hydroxyapatite since June 2025. At that time, my front teeth had begun to appear somewhat translucent. When I asked my dentist about it I was told it was due to my age (52) and losing minerals & enamel in/on my teeth. After some research, I discovered nano-hydroxyapatite and figured, ‘why not’?
My teeth have always been sensitive and my gums prone to bleeding. I have always used Sensodyne and was unsure of changing but I have found my teeth ate less sensitive now.
I just had my 6 month check up & my gums hardly bled & my front teeth are far more ‘solid’ looking! The hygienist complimented me on my improvement since the last check up. All I’ve done differently is the toothpaste!
I am not certain if the toothpaste is the reason (due to lack of fluoride) for my new symptom of dry mouth but I haven’t begun any new Rx’s. I am thinking it is the toothpaste because the products I found to aid with dry mouth all contain fluoride. Just a heads up.

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.
