Mouth rinse or mouthwash is a product used for oral hygiene. Antiseptic and anti-plaque mouth rinse claims to kill the germs that cause plaque, gingivitis, and bad breath. Anti-cavity mouth rinse uses fluoride to protect against tooth decay. Mouth rinses are generally classified either as cosmetic, therapeutic, or a combination of the two.
Cosmetic rinses are commercial, over-the-counter (OTC) products that help remove oral debris before or after brushing, temporarily suppress bad breath, diminish bacteria in the mouth, and refresh the mouth with a pleasant taste.
Therapeutic rinses have all of the benefits of cosmetic rinses but also contain an added active ingredient that helps protect against some oral diseases. Therapeutic rinses also can be categorized according to use: anti-plaque/anti-gingivitis rinses or anti-cavity fluoride rinses, for example. Dentists will prescribe special rinses for patients with more severe oral problems, such as cavities, periodontal disease, gum inflammation, and xerostomia (dry mouth). Therapeutic rinses also are strongly recommended for those who can’t brush due to physical impairments or medical reasons.
