Waterpik Ultra delivers water pressure of 10-90 PSI and 1,200 pulses per minute.

The Waterpik Ultra goes way beyond flossing to keep your gums their healthiest. Waterpik has designed the WP-100 to deliver a water pressure of 10 to 90 PSI with 1200 pulses per minute. This system delivers a clinically proven combination of water pressure and pulsation to remove debris and bacteria lodged deep between teeth and below the gum-line -- three times deeper than brushing alone. In addition, it massages and stimulates the gums to improve circulation and help promote strong and healthy gums. The Waterpik Ultra is so effective that it is clinically proven to be up to 93-percent more effective than flossing at reducing gum bleeding -- a key indicator of impending gum disease.

In fact, there are over 50 published clinical studies that show the Waterpik Dental Water Jet provides significant oral health benefits, for people who wear braces, have diabetes, and have mild to moderate gum disease. That's why Waterpik is the most recommended brand by Dental Professionals. In addition to healthier gums, there is nothing better than the clean, refreshing feeling you'll get after using the Waterpik Ultra. While floss can often leave your gums bleeding, swollen and generally beaten up, the WP-100 makes your mouth feel great. Waterpik guarantees healthier gums in just 14 days. If, after using the Ultra for two weeks, your gums are not healthier, or if you are dissatisfied for any reason, then simply return it for a refund -- no questions asked.
