The Hidden Smoke in Your Mouth: How Listerine Lists Into Every Cigarette Ring Ever noticed a lingering trace of smoke lingering in your mouth after a cigarette—something subtle but unmistakable? Your breath isn’t just carrying the aroma of tobacco; it may also hold traces of Listerene, the iconic mouthwash. While you associate Listerene primarily with freshening breath, newer studies reveal a surprising connection: residual smoke particles and active ingredients from cigarettes can linger in your oral cavity, and surprisingly, Listerene counts some of these trace compounds among them. ### What Is Listerene and How Does It Work? Listerene, a beloved name in oral hygiene, has long been celebrated for its powerful antiseptic properties and breath-freshening capabilities. Its key ingredient, clorhexidine gluconate, targets the bacteria responsible for plaque, gingivitis, and bad breath. But beyond plaque control, Listerene’s formulation interacts with substances introduced through smoking—a connection often overlooked.
