Water Flossing Found To Be a Top Tool For Reducing Gingivitis

Research demonstrates the safety and efficacy of water flossers in maintaining oral health.

Waterpik water flosserDental professionals know that interdental cleaning is a critical component in achieving and maintaining optimal oral health. Traditionally, dental floss is the first tool recommended for interproximal cleaning. Yet this has shifted over the last decade or so, as reviews of flossing and other interdental aids — including water flossing — have yielded results that have disrupted traditional thinking. 

In March 2020, a clinical practice guideline on the treatment of periodontitis (stages I to III) concluded, “We do not suggest flossing as the first choice for interdental cleaning in periodontal maintenance patients.”1 The investigators determined that interdental brushes, including those with rubber/elastomeric filaments, and water flossers reduce inflammation and are preferred by patients.1 This supports a 2018 meta-analysis by Kotsakis et al2 which found that interdental brushes and water flossers ranked high for reducing gingival bleeding, while toothpicks and dental floss ranked last. A 2019 review by Ng and Lim3 provides further support, as the authors determined that interdental brushes and water flossers are effective for reducing inflammation and preferred over dental floss for implant maintenance.

SIGNIFICANT ORAL HEALTH BENEFITS

Several studies have compared water flossing to string floss4–8 and interdental brushes.9,10 In each study, water flossing improved oral health significantly better than string floss or interdental brushes. Barnes et al5 demonstrated that the water flosser was superior to string floss when paired with either a manual or power toothbrush, thus concluding it was the water flosser that provided the additional oral health benefits. While some believe that string floss is still required when using a water flosser, studies indicate it is unlikely patients would realize an additional benefit from adding string flossing to a water flossing regimen. 

STUDIES SUPPORT SAFETY AND EFFICACY

Water flossing is safe and effective. The Waterpik brand of water flossers is supported by more than 80 published scientific studies. This depth of scientific support has earned the Waterpik water flosser the American Dental Association Seal of Acceptance for safety and efficacy.
