Waterpik™ 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.

Objective

To evaluate the effectiveness of the Waterpik™ Water Flosser, when paired with either a power or manual toothbrush, compared with a manual toothbrush and floss, in reducing gingivitis, bleeding, and supragingival plaque biofilm.

Methodology

One hundred and five subjects participated in this four-week study.

  • Group 1: Waterpik Water Flosser plus manual toothbrush

  • Group 2: Waterpik Water Flosser plus power toothbrush

  • Group 3 (control): Manual toothbrush and dental floss

Participants brushed twice daily and used either the water flosser or floss once daily.
Plaque biofilm, bleeding, and gingivitis were assessed at two and four weeks.

Results

After four weeks, the addition of a Waterpik Water Flosser resulted in significantly better oral health outcomes than manual brushing and flossing, regardless of toothbrush type used. Using the Waterpik Water Flosser was up to 93% more effective at reducing bleeding and up to 52% more effective at reducing gingivitis compared with traditional dental floss.

Conclusion

The Waterpik Water Flosser is a significantly more effective alternative to traditional dental floss for reducing gingivitis and improving overall gum health.
