does not wow but it does work [SEP] this product i will say works without making my teeth sensitiveas another reviewer said you definitely want to brush your teeth in the shower because i do not know how but it ends up everywhere if you have disposable rubber gloves i would use that because it will stain under your nails and have a select toothbrush because it will stain your toothbrush it will also temporarily stay in your tongue it does not have a strong vanilla or mint flavor it does not taste bad it just does not really have a taste to it from what i read you do not want to use it more than days because it is abrasive to the teeth so i will definitely be periodically using this
