A breath freshener is a product designed to improve the freshness of a person's breath. These products can come in various forms, including mints, sprays, gums, and lozenges. They often contain ingredients like menthol, eucalyptus, or xylitol to mask bad odors and promote a pleasant taste. Many breath fresheners also have antibacterial properties that help reduce the bacteria in the mouth, which can contribute to bad breath. Regular use can enhance oral hygiene and provide a quick solution for freshening breath after meals or during social interactions.
