Prevention and Hygiene
Mouthwash (mouth rinse)
Mouthwash, or mouth rinse, is a liquid you swish in your mouth. Some kinds help reduce plaque, gingivitis and cavities, and others only freshen breath.
Mouthwash is not a replacement for daily brushing and flossing, but it may be a helpful addition for some people. MouthHealthy says it can reach areas a toothbrush cannot and may help prevent or control tooth decay, reduce plaque, reduce gingivitis, slow tartar, and freshen breath.
There are two main types. Therapeutic mouthwashes have active ingredients that can help reduce plaque, gingivitis, and cavities. Those with fluoride help remineralize enamel. Cosmetic mouthwashes may only reduce bad breath for a short time.
Look for the ADA Seal of Acceptance. Mouthwash is not recommended for children younger than 6, who may swallow it. Talk to your dentist about whether you need one. See oral hygiene, gingivitis, and chlorhexidine rinse.
