Works well, just messy
I like this product as I did notice it made my teeth look whiter, but it got stuck in my gums. Luckily, I have a waterpik that I used to clear out the black particles, because it was very hard to get rid of the black by just swishing water around. I honestly would just recommend whitening strips, but this is a good alternative for the price and if you want a natural alternative.
