Marvis Strong Mint Mouthwash

While its drugstore brethren may be an eyesore on the bathroom counter, the Marvis Stong Mint Mouthwash concentrate puts just as much emphasis on the design of its packaging as what's inside the bottle. This highly concentrated, alcohol-free formula lasts longer than you think too: Blend it with four parts water to every one part of mouthwash, and it keeps gingivitis, tooth decay, plaque, and bad breath at bay. You did remember to floss and brush first, right?
