Does not burn and smaells tastes good
This mouthwash does not burn, even after flossing.  It lingers with protection for several hours. Although not 12 hours that is refered to by Colgate.<br /> I have not had any black stains after 3 weeks use.  I only use it one time a day though.<br />This is an okay product, just as good as any colgate I've used, but I can't say I notice a huge improvement over the regular total mouthwash.
