Pulsating Streams for Healthier Teeth and Gums
The Waterpik Ultra Cordless Dental Water Jet goes beyond flossing to keep your teeth and gums healthy and clean. Waterpik has designed the WP-450 to deliver precisely controlled pulsating streams of water pressure to remove debris and bacteria lodged deep between teeth and below the gumline. In fact, it has been shown that the WP-450 can clean three times deeper than brushing alone. In addition, it massages and stimulates the gums to improve circulation. The WP-450 helps promote strong and health gums, leaving you with a clean, fresh mouth sensation.

According to Waterpik, there are over 50 published clinical studies that show the Waterpik Dental Water Jet provides significant oral health benefits for anyone who desires healthier teeth and gums. These studies also show that the WP-450 is especially effective for those who have braces, implants, crowns, bridges, and other dental work. For these reasons, Waterpik is one of the most recommended brands by dental professionals.

Rating : - Great overall, few flaws
I was always sceptic about the waterpick versus flossing. But this product does work the same and maybe even better. It does get the teeth very clean, in every little pocket. I have braces and it works great around them with the standard tip. No more touching the gross floss :))
Pros: Gets the teeth sparkling clean. Period.
Cons: The tip DOES rotate easily, like other reviewers mentioned. Not sure if it's a safety issue, but it is rotating way too easy. Workaround - I just hold it by the tip instead of the body and regulate it.
The tank does empty very fast, but the workaround - just keep the faucet running and from time to time just fill in the water without stopping, just bend low :) It works fine and saves time.
