Product overview
Waterpik Cordless Plus Water Flosser Rechargeable Oral Irrigator with 4 Tips and 2 Pressure Settings - White
Elevate your daily oral hygiene routine with the clinical power of the Waterpik Cordless Plus Water Flosser. Engineered as a highly effective alternative to traditional string dental floss, air flossing, and interdental brushes, this portable oral irrigator delivers deep-cleaning action between teeth and well below the gumline where standard toothbrushes cannot reach. By pairing micro-pulsations with a customizable water pressure range, it sweeps away stubborn plaque bacteria, food debris, and subgingival pathogens to help control gum inflammation, reverse gingivitis, and prevent potential bone or tooth loss.
Key benefits
-
Clinically Proven Gum Health: Up to 50% more effective than standard dental floss for improving overall gingival health and reducing bleeding gums.
-
Maximum Plaque Eradication: Scientifically verified to eliminate up to 99.9% of plaque biofilm from treated areas within a 3-second application window.
-
Orthodontic & Implant Optimization: Up to 3X as effective for cleaning around metal braces when using the Orthodontic Tip, and up to 2X as effective for maintaining tissue health around implants with the Plaque Seeker Tip.
