Easy to Use and No Bad Taste
I really like this whitening powder, it’s easy to use and fits nicely into my routine. It works well as an alternative to regular toothpaste, and the process feels simple and quick. One of the best things is that there’s no bad taste. It has a mild, clean flavor that makes it comfortable to use daily, even if you’re sensitive to strong or overpowering mint products. After using it consistently, it seems to be working my teeth look a bit brighter, and it feels gentle enough for sensitive teeth without causing discomfort. Minor note: Since it’s a powder, it can feel a little different at first compared to traditional toothpaste, but it’s easy to get used to. Overall, this is a convenient and gentle whitening option that’s easy to stick with. A great choice if you want something effective without harsh taste or sensitivity.

Whitens but not a pleasant taste.
Yes, it whitens teeth but is abrasive. Not sure how good it is for enamel, and it tastes terrible.

Great Toothpaste Alternative
I really like this teeth whitening powder. It is easy to use and leaves my mouth feeling clean and fresh. I also appreciate that it is made with nano hydroxyapatite and is designed for sensitive teeth. It has become a great addition to my oral care routine, and I am very happy with this product.

it's not bad
a coffee, tea, and alcohol drinker so i've gone thru a few of these. i knew i wouldn't see immediate results so i just tried to consistently brush my teeth with this. i can't say it made my teeth whiter but i think it brightened my teeth and helps to prevent it from staining? i didn't irritate my teeth or gums which is important, it helped my mouth to feel cleaner or was it bc of the flavors in it that makes it feel like that? also this little container is too expensive!
