Antibacterial mouthwashes are oral hygiene products that are designed to kill bacteria in the mouth. They contain active ingredients such as chlorhexidine, cetylpyridinium chloride, and essential oils that help to reduce plaque, gingivitis, and bad breath. These mouthwashes are typically used after brushing and flossing to provide an extra layer of protection against oral bacteria. While they are not a substitute for regular brushing and flossing, they can be a useful addition to your oral hygiene routine.
