My New Go-To for Gentle Everyday Care!
Color: White
I’ve been loving my Boka Classic Manual Toothbrush, it’s truly transformed my brushing routine! 🪥 The extra-soft, activated-charcoal-infused bristles feel so gentle yet effective, especially along the gumline. They clean thoroughly without scratching or irritating sensitive gums, which has made a noticeable difference in comfort and overall oral health.

Get Yourself A Bright White Smile
Can't belive how great this works. You can actually see the staining it removes when you expel to rinse. A bit messy to use all be it being a powder. The taste isn't bad. I believe this works better than the whitening stripe, which to me are difficult to use. Gentle on your gums and teeth. I do not recommend and do not believe the manufacture does either to use on a daily basis. A bit pricey but so are the whitening strips. For a bright white smile I recommend this product.

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.
