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.
