According to the American Dental Association, using a water flosser (a.k.a. oral irrigator) is a smart choice to remove plaque, reduce gingivitis, keep your mouth clean and your smile bright. Experts suggest that you use a water flosser every day in addition to your normal brushing and hand flossing routine, instead of replacing regular flossing with a water flosser. That said, some people aren’t able to floss by hand, in which case, a water flosser can be an excellent substitute. Try one of these to improve your oral health.
