Smart Technology, Blocking Sulfur Gas
SmartMouth™ Mouthwash works longer than other mouthwashes because you activate it right before rinsing, combining the two solutions as you pour. This releases an abundance of zinc ions, which are the key to eliminating* and blocking sulfur gas – the real cause of bad breath.
Killing germs alone is not enough to eliminate bad breath for more than an hour or so. Long-lasting fresh breath requires smarter technology.
