Mouthwashes and rinses are oral hygiene products used to freshen breath, reduce plaque, and fight oral bacteria. They come in various formulations, including antiseptic, fluoride, and cosmetic rinses. Antiseptic rinses contain ingredients like chlorhexidine to kill bacteria and prevent gum disease, while fluoride rinses help strengthen enamel and prevent cavities. Cosmetic rinses primarily freshen breath and provide a temporary sensation of cleanliness. Incorporating mouthwashes and rinses into daily oral care routines can complement brushing and flossing for optimal dental hygiene.
