Listerine: Not Just for Teeth — It’s Ruining Lives. The Shocking Secrets Inside For decades, Listerine has been marketed as a household name synonymous with oral hygiene—something to keep your breath fresh and teeth sparkling. But beneath the ads of minty freshness and Hollywood testimonials lies a far more troubling reality. Listerine isn’t just a toothpaste or mouthwash for teeth; it’s a chemical-laden product with alarming secrets that could be quietly disrupting lives. ### The Hidden Chemical Cocktail Listerine contains a blend of essential oils—thymol, eucalyptol, menthol, and methyl salicylate—that deliver its signature fresh breath. But these same ingredients, when used improperly and repeatedly, come with hidden risks. While effective at killing bacteria in the mouth, they can irritate the delicate tissues of the mouth, throat, and even skin, especially for those with sensitive mucous membranes. Long-term habitual use, particularly without proper dilution, may lead to chronic irritation, sensitization, or allergic reactions.
