The Waterpik® Dental Water Jet: Clinically Proven Results

One of the first studies published in the late 1960s demonstrated that the Waterpik® dental water jet could significantly reduce gingivitis and calculus. Since then, over 50 studies have been conducted in 25 universities and independent research facilities. Collectively, they demonstrate that the Waterpik® dental water jet is safe, effective and provides superior oral health results.

Recent studies have addressed the changing dynamic of dentistry and evaluated the effect on plaque biofilm and the response to inflammation in individuals with diabetes. We have also answered the age old question – Can the Waterpik® dental water jet help my patients who won’t floss? - A resounding yes!
