Water Flossers Overview

Water flossers are handheld devices that spray water between your teeth in steady pulses. Like traditional flossing, water flossers remove plaque and food particles between your teeth. 

Studies show water flossers are effective at removing plaque. However, there are no studies confirming they can prevent cavities between your teeth the way floss can.1, 3

Taking care of your oral hygiene from an early age is essential for long-term cavity and gum disease prevention.

How Do You Use a Water Flosser?

Using a water floss is simple. Here are the steps:

  1. Fill the reservoir with water or connect it to the tap. 
  2. Follow the instructions for your specific product. For example, many manufacturers do not recommend adding more than a 1:1 ratio of mouthwash. This ensures you do not damage the water flosser. 
  3. Select a tip and attach it to the water flosser.
  4. Lean over the sink and place the nozzle into your mouth. 
  5. Select a low pressure and turn the flosser on. The pressure should be comfortable. You can gradually increase the pressure as necessary.
  6. Start with the molars. Direct the water to the gum line and the areas between the teeth.
  7. Hold the water over each tooth for a few seconds. Be sure to cover the inside and outside of the teeth.
  8. Repeat the process on all teeth. 
  9. Turn the unit off and remove the tip.
  10. Drain any remaining water and rinse the reservoir. Do not leave water in the reservoir, as this can cause bacteria to grow.

Is Water Flossing Better Than Traditional Flossing? 

The American Dental Hygienists' Association (ADHA) recommends water flossing over traditional flossing.10

Some people prefer water flossing because it's easier to get into the teeth’s crevices. You may also find it more effective if you have dental work, including:

Also, conditions like arthritis or certain disabilities can make using hands and fingers difficult. If you have trouble maneuvering string floss, a water flosser may be a good option. 

No studies have determined if water flossers can help prevent cavities in between the teeth as well as string floss. For this reason, many dentists recommend water flossers as an oral hygiene adjunct rather than a replacement for string floss. 

What Does Science Say?

Water flossers have been evaluated multiple times since the first model was introduced in 1962.2 Research shows that water flossers have advantages over traditional floss in several key areas:

1. Effectively remove plaque

In one study, researchers compared two groups of people. One group used a water flosser and the other used string floss. Both groups also used manual toothbrushes.

The researchers found that water flossing was far more effective. The water flosser group had an almost 75% reduction in overall plaque. For the string floss group, the reduction was around 58%.3

Researchers concluded that a water flosser and manual toothbrush were significantly more effective at removing plaque than string floss and a manual toothbrush. 

2. Clean around orthodontic appliances

Orthodontic appliances such as braces can be difficult to keep clean. Plaque and gingivitis often increase following their placement. Water flossing helps reduce these problems.  

A study of 106 people with fixed dental appliances compared water flossing, string flossing, and no flossing. The people who used a water flosser had significant reductions in bleeding and plaque.4

3. Safe to use around implants

Correct maintenance of dental implants is essential to prevent implant failure. Therefore, dentists often recommend water flossing.

An early study compared two groups of people with dental implants. The first used a 0.06% chlorhexidine solution delivered with a water flosser. The second group used a traditional 0.12% chlorhexidine rinse without a water flosser. The results were significantly better in the water flosser group:

  • The plaque was reduced by 29% vs. 9%
  • Bleeding was reduced by 62% vs. 33%


Water flossers use a stream of pressurized water to clean the teeth. These handheld devices remove plaque, food particles, and other debris. 

Studies show water flossers are very effective at removing plaque between teeth. To ensure you're buying a quality product, look for the American Dental Association (ADA) Seal of Acceptance. These water flossers have been shown to help prevent gum disease, cavities, and other oral health issues.
