it works [SEP] i ve been using this product for days once or twice a day and have already noticed a difference as others have said make sure you don t wear anything nice while brushing because this stuff gets everywhere you will need to brush and floss afterwards this is not a substitute for toothpaste by any means i went ahead and bought a different toothbrush to brush with this since i noticed my regular electric toothbrush head was still pretty dark after rinsing
