WaterpikTM Water Flosser: Over 50% More Effective than String Floss for Reducing Gingivitis

Comparison of Irrigation to Floss as an Adjunct to Toothbrushing: Effect on Bleeding, Gingivitis, and Supragingival Plaque

Barnes CM, et al. J Clin Dent, 2005; 16(3): 71-77. Study conducted at the University of Nebraska Medical Center, College of Dentistry, Lincoln, Nebraska.


To evaluate the ability of a WaterpikTM water flosser paired with either a power or manual toothbrush, and a manual toothbrush and floss, to reduce gingivitis, bleeding, and supragingival plaque biofilm.


One hundred five subjects participated in this four-week study. One group used a WaterpikTM water flosser with a manual toothbrush and a second group used the WaterpikTM water flosser with a power toothbrush. The control group used a manual toothbrush and floss. Subjects brushed twice daily and used either the water flosser or dental floss once daily. Plaque biofilm, bleeding, and gingivitis were evaluated at two and four weeks.


At four weeks, the addition of a WaterpikTM water flosser resulted in significantly better oral health, regardless of toothbrush type used over manual brushing and flossing. Adding the WaterpikTM water flosser was up to 93% better in reducing bleeding and up to 52% better at reducing gingivitis than traditional dental floss.


The WaterpikTM water flosser is an effective alternative to traditional dental floss for reducing gingivitis.
