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.
Our team has put together a list of the best cordless water flossers available. We took into account the:
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.- NCBI
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.
One study found that water flossers were 29 percent more effective than floss for overall plaque removal.- NCBI
Before purchasing a cordless water flosser, it is essential to look for the following features to ensure you are buying the best product:
Using a water flosser is a straightforward process:
The Waterpik Cordless Advanced is compact and does not have a large water reservoir. This model comes with four different flossing tips, three pressure settings, and 360-degree tip rotation.
It also features a magnetic 4-hour rapid charging system, a waterproof design, and an ultra-quiet operation. It's perfect for small spaces, travel, and can even be used in the shower.
The ION Cordless Water Flosser provides maximum performance with cordless convenience. It is 30% smaller in size than traditional plug-in Waterpik models, so the ION is incredibly compact. The rechargeable cordless design also eliminates clutter, making it ideal for small bathroom counters.
ION’s rechargeable lithium-ion battery lasts up to four weeks per charge. It also features a convenient magnetic handle cradle and an on/off water control on the handle.
Philips Sonicare AirFloss Ultra is designed for inconsistent flossers and has the ADA Seal of Acceptance. You can fill the water reservoir with mouthwash or water to provide a deep clean. The irrigator is proven to be as effective as floss for gum health and cavity prevention.
Sonicare’s AirFloss also has a slimmer profile and better portability than most water flossers. This makes it possible to use half the liquid of a normal oral irrigator. Unlike other flossers, it shoots out air and water only when you press a button, making it a less messy option.
The Waterpik Cordless Freedom is portable and waterproof. It's great for small spaces, travel, or use in the shower.
It comes with three tips and two pressure settings. It runs on AA batteries, so no charging is required.
Best Cheap Cordless Water Flosser
This water flosser is the most affordable on the list (just under $30). It also has a ton of value for the cost. For example, it is waterproof, includes five water pressure settings, and lasts 15 days with a full charge. It also has a gravity ball at the end of the tube to ensure the water comes out completely (no matter the flossing direction).
The 360-degree rotatable nozzle allows you to clean areas that are difficult to reach with a toothbrush. The device’s cleaning power also helps prevent cavities, plaque and calculus buildup, tooth sensitivity, and bleeding gums.
The H2ofloss is cordless, lightweight, and great for traveling. They will refund you in full within 30 days if you are unhappy with your purchase. If your water flosser breaks within 12 months, they will send you a replacement for free.
