Antibacterial mouthwashes are a popular oral hygiene product that helps to kill bacteria and reduce plaque build-up in the mouth. These mouthwashes contain active ingredients such as chlorhexidine and cetylpyridinium chloride that work to kill bacteria and prevent gum disease. They also leave the mouth feeling fresh and clean. Some antibacterial mouthwashes are alcohol-free, making them a good option for those with sensitive teeth or dry mouth.
