Listerine Professional Gum Therapy

**Listerine Professional Gum Therapy** is a locally applied oral-rinse product for treatment and prevention of gingivitis. Current official Norwegian labeling identifies ethyl lauroyl arginate hydrochloride as the active antimicrobial ingredient at 0.14% w/w and classifies the product as a medical device; the product is intended to form a protective barrier on the acquired enamel pellicle that reduces bacterial adhesion and dental-biofilm formation. ([listerine.no](https://www.listerine.no/produkter/listerine-professional-gum-therapy)) A randomized 21-day experimental-gingivitis study of the branded product formulation described at the time as containing ethyl lauroyl arginate plus essential oils reported lower plaque scores than controls without mechanical cleaning, but concluded that residual plaque was sufficient to cause gingivitis and questioned the clinical benefit of the rinse alone.
