Mouthwash showdown: which rinse best fights gum disease?

This study tested two mouthwashes—one with 0.12% chlorhexidine and another with a lower dose of chlorhexidine plus cetylpyridinium chloride—to see which better controls gum inflammation and bacteria in people with gum disease. 72 adults used one of the rinses for a month after a professional cleaning, and their gum health was tracked for six months. The goal was to find a gentler but equally effective option for long-term gum disease management.
