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!

Great Product

Its a good product. It works gradually whitening teeth. I use this powder on top of the Boka Prebiotic toothpaste and I have to say I am pretty impressed how clean my teeth are, the whitening and no sensitivity issues.
