What are Cordless Water Flossers?

Cordless water flossers are handheld dental devices that spray water between your teeth in constant pulses. They offer a convenient, quick, and effective way to floss your teeth daily.

Countertop water flossers (corded models) require power to work. These devices are also larger, take up counter space, and are not easy to travel with. 

Portable water flossers (cordless models) do not require power. They are rechargeable, compact, easy to pack, and don’t take up counter space.

Why Trust Us?

Our team has put together a list of the best cordless water flossers available. We took into account the: 

  • Battery life
  • Quality of features
  • Reviews from multiple sites 
  • The trustworthiness of the brand
  • Portability
  • Pressure modes 
  • Overall value for the money

Some water flossers have the American Dental Association (ADA) Seal of Acceptance. These water flossers are effective in preventing gum disease, cavities, and other oral health conditions. 

Devices that currently have the ADA Seal of Acceptance include Philips and Waterpik Water Flossers. We chose the best flossers with this seal of acceptance, which you will read more about below. 

Other devices included in this article do not have the ADA Seal of Acceptance. However, after hours of research, our team determined they were still effective in removing plaque and preventing common oral health conditions (e.g., cavities and gingivitis). 

We determined each brand's reputability by speaking with company leaders, reading hundreds of customer reviews, and ensuring they provide quality customer service.

Water flossers have been shown to reduce gum bleeding, gingivitis, probing pocket depth, and calculus buildup on teeth.


Dental Water Flossers vs. Traditional Floss 

Unlike traditional flossing, water flossers use high pressure water to remove plaque and food particles between your teeth. Water flossers provide some additional benefits over traditional dental floss. For example, they offer a deeper clean with the use of water, jet tips, and different cleaning modes. 

Water flossers also have 360-degree rotatable nozzles, allowing for a more effortless clean in hard-to-reach areas. This helps prevent plaque buildup on your molars, gum line, and keeps your entire mouth fresh. 

Benefits of water flossers over regular floss include:

  • They remove more plaque between your teeth and along the gum line
  • They massage your gums, which helps keep them healthier
  • They do not make your gums hurt
  • They make it easy to clean between braces, implants, and bridges
  • They are convenient 
  • They clean between your teeth very quickly
  • They are ideal for people with arthritis or limited mobility (dexterity)
  • They are cost effective

One study found that water flossers were 29 percent more effective than floss for overall plaque removal.

Before purchasing a cordless water flosser, it is essential to look for the following features to ensure you are buying the best product:

  • Long battery life (rechargeable or battery-operated)
  • 30+ second flossing timer
  • 360-degree tip rotation for a deep clean
  • A variety of flossing tips
  • Waterproof design
  • Leakproof design
  • Warranty
