Therapeutic mouthwashes use antimicrobial ingredients to kill the bacteria that can cause plaque, gingivitis, bad breath, and tooth decay. Depending on the ingredients, these mouthwashes are available over the counter or by prescription.
Mouthwashes without these antimicrobial ingredients are considered to be “cosmetic.” They’re useful for freshening breath, but don’t reduce your risk of cavities or gum disease.
