Twice Nano-Hydroxyapatite Toothpaste, Fluoride-Free - Activated Charcoal for Teeth Whitening, ICY Mint - 3.4 oz

I buy it for the hydroxyapatite which strengthens enamel. Wish it also had stannous fluoride which also strengthens enamel. I don't care about the charcoal.

Love this tooth paste! Doesn't make my mouth sting and hurt afterwards. It also isn't gritty and it doesn't make my mouth dry. As far as making my teeth more white, I really haven't noticed a difference.

Helps with sensitivity, minty taste. Takes a little time to get use to not having tons of bubbles while brushing! Will splatter all over your sink and stick to your tongue but knocks out tooth pain.

Can't beat the price for sure. Charcoal really works on brightening your teeth too. Fluoride free is a obviously going to be game changing for your health long term.

The price is great for a toothpaste that has hydroxyapatite. Maybe the charcoal in it isn't such a great idea, IDK. Been using this for about 18 months and don't notice any downside/negatives.

After thoroughly brushing my teeth with this new toothpaste, my partner told me it it smelled like I had morning breath, and it was 5 PM This toothpaste has no minty flavor and the charcoal gray color temporarily stained my white bathroom sink I did experience my teeth tingling very often, even after brushing my teeth hours later, hoping the ingredients were actually repairing my enamel like it says, I kept using it. However, the bad breath issue is making me not want to continue using this product

Excellent product that I have used before. However, this is my first time ordering it online for in-store pickup. Product info states to not use if box is open or seal is broken. The protective seal is completely missing.

Although it may be Fluoride free, the other ingredients remain bad. Got it delivered and was able to scan it after receiving. Does not have a strong mint flavor either

Taste is pretty bad, even trying a smaller than normal amount. It was on sale and bragged about being natural and soapless. Using a few apps, it only rates 44- 46 :100 for being healthy. It doesn't contain traditional soap thickeners but it still has a list a mile long of any chemical they could find.

I wanted to try the remineralization of teeth. similar like products projected further damage to teeth over time. I've got all teeth and trying to rebuild them to the extent possible. Not wear them down further
