Clinically Proven Results

Good oral health takes work. For years, dentists and hygienists have encouraged flossing for cleaning between the teeth. However, many of these professionals and their patients know that flossing is not easy. But there is good news: clinical research studies now confirm the Waterpik Water Flosser is The Easy and More Effective Way to Floss.

Recent studies show the Water Flosser is up to 50% more effective than traditional dental floss and Sonicare® Air Floss Pro for reducing gingivitis and improving gum health. Whether using a manual or sonic powered toothbrush, adding the Water Flosser has consistently provided significantly better reductions in plaque and gingivitis.

Waterpik's impressive record for safety and effectiveness has been evaluated in more than 55 published clinical studies at 25 independent and university-based research centers.
