What is a Waterpik?

A water flosser is an oral health device that sprays streams of water in steady pulses. Similar to traditional dental floss, the water removes food particles, bacteria, and plaque between your teeth.

Waterpik® is the most well-known and respected water flosser brand. According to Waterpik, 9 out of 10 dental professionals recommend these water flossers over other brands.

Waterpik Flossers

Waterpik sells over 20 different types of water flossers, including:

  • Countertop water flossers for deep cleaning
  • Compact countertop water flossers for small spaces and travel
  • Handheld, battery-operated water flossers
  • Travel-size water flossers
  • Toothbrush and water flosser combos
  • Complete oral care kits
  • Whitening water flossers

The brand also sells many different types of flossing tips and accessories. These tips have different cleaning features and can be swapped out at any time. For example, if you have gum disease, you’ll benefit from using the Pik Pocket™ Tip with your Waterpik. It accesses up to 90% of the depth of 6mm gum pockets.

How Effective are Waterpiks?

To determine Waterpik’s effectiveness, we compiled a list of clinical research studies. We also compared Waterpik to traditional string floss and other water flosser competitors:

Clinical Research and Statistics

Waterpik’s website has 26 research articles that review the effectiveness of the brand’s water flossers.8 

In one study, the Waterpik® Water Flosser was found to be more effective than string floss in adolescent patients with braces. The device was over 3X more effective than floss and over 5X more effective in removing plaque than brushing alone.6 The researchers also found that Waterpik was 26% more effective in reducing gingival bleeding in orthodontic patients (using the Orthodontic Tip). 

Another study found that the Waterpik® Sonic–Fusion® and traditional flossing/brushing significantly reduced plaque. However, the Sonic–Fusion was more than twice as effective in reducing plaque, gum bleeding, and gum inflammation.12

In addition to plaque removal and improved gum health, Waterpik is also effective at stain removal. A study found that the Waterpik® Whitening Water Flosser improved stain reduction by 25% over brushing alone (after two weeks).8  

Waterpik has also been proven to be safe in clinical studies for over five decades.10 

Waterpik vs. Other Competitors 

Waterpik is the most trusted and well-known brand of water flossers.

Waterpik Water Flossers also have the American Dental Association (ADA) Seal of Acceptance. This means that these devices are proven to be effective in preventing gum disease, cavities, and other oral health conditions. 

“The ADA Seal of Acceptance provides consumers with the assurance that the advertising claims about a product are scientifically sound and valid. The Seal is a symbol of safety and efficacy for over-the-counter dental products. The program began in 1931, and in 1984, President Ronald Reagan gave the ADA a certificate of commendation for the outstanding self-regulatory efforts of its Seal Program.”


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.

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 are now starting to recommend these devices over traditional floss. Waterpik is the most trusted brand (because it has the ADA Seal of Acceptance). 

Benefits of Waterpiks

  1. Up to 2x more effective in removing plaque than regular brushing and flossing12
  2. 2x more effective at improving gum health around dental implants than floss9
  3. Up to 3x more effective in removing plaque around braces than string floss6
  4. Up to 50% more effective in improving gum health than string floss11

Downsides of Waterpiks

  • Can leak and lose strength over time
  • Messier than string floss
  • Can be difficult to upkeep (change the water in your device to prevent mold and bacteria growth)
  • Battery-operated devices require charging, making string floss more convenient
  • Much more expensive than traditional floss

Frequently Asked Questions (FAQs)

Who can use a water flosser?

Anyone can use a water flosser. 

Who should not use a water flosser?

People with very sensitive gums may find it difficult to use water flossers. Children can also use water flossers. However, they might not be good candidates since most kids don’t have established oral health routines.

For best results and plaque removal, brush your teeth before you floss. 

When should I replace my water flosser tip?

Waterpik recommends changing your flosser tip every three to six months. 

Can multiple people use a water flosser with different tips?

Yes. A ring at the base of each tip is color-coded for easy identification. 

How do I clean the flosser tips?

Remove the tip using the eject button, soak it in hydrogen peroxide for 5 to 7 minutes, and then rinse it under warm water.
