Water flossing is a way to clean between and around your teeth. A water flosser is a handheld device that sprays streams of water in steady pulses. The water, like traditional floss, removes food from between teeth.

Water flossers have been tested to be safe and effective at removing a sticky film called plaque, which puts you at a higher risk for cavities and gum disease. Water flossers can also help reduce gingivitis, the early form of gum disease, throughout your mouth and between your teeth. 

Water flossers can be an option for people who have trouble flossing by hand. People who have had dental work that makes flossing difficult—like braces, or permanent or fixed bridges—also might try water flossers.

Cleaning between your teeth once a day is an important part of your dental hygiene routine. You should also brush your teeth twice a day for two minutes and see your dentist regularly.
