I’m a big coffee drinker, and snow is my favourite whitening product. I use the gold ones and I’m maybe using it once or twice a week. It’s not painful at all, very easy to use, and makes my teeth look nice and white. I can enjoy drinkIng all the coffee I like.
I have found Snow works best with a really good quality electric toothbrush, as they remove a lot more plaque than standard electric tooth brushes and make your teeth look beautiful and healthy.
