See the results for yourself!
This stuff works really well! I noticed results after the first try. I've convinced friends with yellow teeth to try it and it works really well for them too!
I was a bit skeptical about trying this, but I have sensitive teeth and can't use strips so I thought I'd give it a shot and have been really pleased with the results. I also use the charcoal toothpaste they give you and I love how clean it makes my mouth feel!
I tried this after it was recommended to me by a friend. I saw my teeth become 3 shades whiter over the course of a week and couldn't be happier!
I'm not one that reviews a lot of product, but I was just so impressed by this after just one use that I had to share! Just look at the difference.
So I've been using this for about a month now, and the results have stayed. I was worried that it would be temporary, but they aren't. Seems pretty permanent to me, as long as I don't stain them as I'm a heavy coffee drinker.
