Water Flosser more effective than interdental brushes

Two recent pilot studies conducted at an independent research facility compared the effectiveness of a Water Flosser to interdental brush use on bleeding and plaque scores. Both studies demonstrated that the Water Flosser was significantly more effective than an interdental brush at improving oral health.

Water Flosser vs. Interdental brush: reduction of gingival inflammation

Twenty-eight subjects completed this two-week study. Fourteen subjects were assigned to use either:

  • Water Flosser + manual toothbrush
  • Interdental Brush + manual toothbrush

Subjects were instructed to brush twice daily and use their assigned interdental cleaning device once in the evening.

Results: The Water Flosser was 56% more effective at reducing whole mouth bleeding and 53% more effective at reducing interproximal bleeding than the interdental brush.

Conclusion: The Waterpik® Water Flosser is significantly more effective than interdental brushes at improving gingival health.

Water Flosser vs. Interdental Brush: single use plaque removal

Twenty-eight subjects completed this single-use plaque study study. All subjects used a manual tooth. Half of the subjects used a Water Flosser and the other half used an interdental brush.

The results showed that the Waterpik® Water Flosser was 18% more effective at removing overall plaque and 20% more effective at removing interproximal plaque than interdental brushes.
