How Cordless Water Flossers Work

A cordless water flosser, also called a portable oral irrigator, cleans between teeth and along the gumline using a focused stream of pressurized water.

The device pumps water from an internal reservoir through a narrow nozzle tip. Pulsating water pressure helps remove plaque, bacteria, and food particles from areas traditional floss may miss.

• Pressurized water dislodges plaque and debris
• Pulsation stimulates gum tissue
• Specialized tips target braces, implants, and gum pockets
