How Effective are Waterpiks?

We compiled a list of clinical research studies to determine Waterpik’s effectiveness. We also compared Waterpik to traditional string floss and other water flosser competitors. Below are the results:

Clinical Research and Statistics

Waterpik’s website has an abundance of clinical research articles that review the effectiveness of the brand’s water flossers. Their products have been proven to be safe in clinical studies for over five decades.10

More Effective Than Traditional Brushing and Flossing

In one study, the Waterpik Water Flosser was over 3X more effective than floss and over 5X more effective in removing plaque than brushing alone.6 

Another study found that the Sonic–Fusion was more than twice as effective in reducing plaque, gum bleeding, and gum inflammation.12

Better Whitening

In addition to plaque removal and improved gum health, Waterpik offers effective stain removal. A study found that the Waterpik Whitening Water Flosser improved stain reduction by 25% over brushing alone.8

Waterpik vs. Competitors 

Waterpik is the most trusted and well-known brand of water flossers. Their devices have the American Dental Association (ADA) Seal of Acceptance, which means it’s proven effective in preventing gum disease, cavities, and other oral health conditions. 

More than 200 products carry the ADA Seal of Acceptance. However, the Waterpik Water Flosser is the first powered interdental product to earn this Seal.7

Philips Sonicare Airfloss Water Flosser also has the ADA Seal of Acceptance. This device is a great alternative to Waterpik. 

Waterpik vs. String Floss

String floss is still the #1 recommended way to floss by most dentists. However, as water flossers become more popular, some dentists now recommend these devices over traditional floss.

  5. Aim the flosser tip at your gums and move it along your gum line.
