Mouthwash is great. It is a liquid antibacterial and plaque dissolving agent, and because it is a liquid, it can reach places that a toothbrush or even dental floss cannot. It is a great way to prevent bad breath, staining, plaque, tooth decay and periodontitis. It can get between, behind and underneath teeth, it can neutralize the plaque that the swishing motion does not remove, and it can coat the tongue, a much overlooked source of bacterial infection that is also a major cause of halitosis. It freshens breath and prevents tooth decay. Perhaps the only negative thing about it is that most store bought mouthwash includes alcohol, which can dry out the mucus membranes, and can cause a conundrum for AA patients. Here are a few at home mouthwash recipes to try, they really work!
