Can't belive how great this works. You can actually see the staining it removes when you expel to rinse. A bit messy to use all be it being a powder. The taste isn't bad. I believe this works better than the whitening stripe, which to me are difficult to use. Gentle on your gums and teeth. I do not recommend and do not believe the manufacture does either to use on a daily basis. A bit pricey but so are the whitening strips. For a bright white smile I recommend this product.
