Bests & Worsts Reviews from Amazon

I have used this product twice now. I will start with the positives: The results are astounding and immediate. My teeth were visibly whiter, shiny and smooth after the first use. My husband said my teeth were "gleaming" I have tried the at-home whitening strips and toothpastes, but they always irritated my gums terribly. This product left my gums tingly. I love that it is all natural, and that it does not use peroxide. The drawbacks are: It's very weird at first, looking like you are brushing your teeth with mascara. It is also very messy - I had black stuff all over the sink. This may get better as I get used to using it. So at least for the first few times, expect that it's going to take you about three times longer to brush your teeth. I also have had to floss afterward to get bits of black from between my teeth, but at least it will force me to remember to floss! I use it with a sonic-care brush, so that does make for more splashing of it around. But to me, so worth it. I drink coffee, tea and wine every day, and I am always worried about my teeth being stained. This really seems to take care of that. Most definitely worth a try!
