Maintain clean, healthy teeth, gums and periodontal pockets with the cordless, easy-to- use Panasonic EW1511W Ultrasonic Water Irrigator. The portable Panasonic EW1511W Compact Dental Water Flosser uses ultrasonic technology for thorough professional oral care with the continuous power of up to 1, 600 ultrasonic water pulses per minute. Water moves through the narrowed water jet nozzle, generating thousands of micro-bubbles that burst on contact with teeth, gums and periodontal pockets. The resulting impact removes food debris on and between teeth and rinses out harmful plaque and bacteria. In just 60 seconds, the rotatable water jet nozzle reaches, removes and cleanses in places dental floss and toothbrushes can\'t. The EW1511W is designed for five essential types for oral care: interdental, periodontal pocket and teeth surface cleaning, plus gums and orthodontic appliance care, and includes five different water pressure settings for individual tooth and gum sensitivities. Smart touch-buttons control water pressure adjustments, and when battery power runs low, a blue LED flashes. During charging, a red LED illuminates. The EW1511W Dental Water Flosser has a sure-grip, ergonomically contoured profile designed to fit naturally in the hand for ease of use and total control, even when the water reservoir is full. This cordless, portable dental cleaning device can be used at home, and its compact design makes it easy to maintain healthy oral care away from home, on business or vacation. The EW1511W fully charges in only 60 minutes for up to 10 minutes of use, and the 6.8 oz. water tank provides 60 seconds of water flossing usage per fill. After use, the IPX7-rated waterproof irrigator washes clean under warm running water. The irrigator\'s stylish charger stand fits neatly on most bathroom vanity sinktops, on shelves or in drawers.
