How does LISTERINE® Work? LISTERINE® Fights Germs with Essential Oils The power of LISTERINE® Antiseptic comes from a formula of four essential oils that kill millions of germs on contact. Our fixed combination of eucalyptol, menthol, methyl salicylate, and thymol continues to deliver unsurpassed results. No other branded mouthwash has this formula. And that"s why no other mouthwash feels or works like LISTERINE®. LISTERINE® Penetrates Plaque Biofilm and Kills Germs Biofilm is a more recent term for the bacterial film on your teeth we call plaque. Biofilm is an organised community of germs in a gooey matrix that enables them to multiply and survive inside your mouth. Brushing and flossing help disrupt and remove this biofilm, but sometimes may miss hard to reach areas—prime real estate for gingivitis causing germs. LISTERINE® Antiseptic rapidly penetrates the biofilm to kill plaque and gingivitis germs.
