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.

Studies suggest that water flossers are as effective, if not more effective, as traditional dental floss1, 2 Water flossers may also be ideal for people with dental implants since they’re less invasive than string dental floss.2, 3

Types of Water Flossers

The types of water flossers are:

  • Portable water flossers (cordless models) do not require power. They are rechargeable, compact, easy to pack, and don’t take up counter space
  • Plug-in water flossers (corded models) must be plugged in to work. These devices are also larger, take up counter space, and are difficult to travel with.
  • Cordless countertop water flossers combine the portability of cordless models with the larger water reservoirs of countertop ones. They’re still compact and don’t need to be plugged in while you use them

What to Look for in a Cordless Water Flosser

The following features are essential to ensure you’re buying a good 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 and leakproof design
  • A clear warranty

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

Water Flossers vs. Traditional Floss 

Water flossers use high-pressure water to remove plaque and food debris between teeth. They have 360-degree rotatable nozzles, so you can easily hard-to-reach areas. This helps prevent plaque buildup on your molars and gum line and keeps your entire mouth fresh.

Traditional floss, on the other hand, is a thin string wrapped around your index fingers and inserted between teeth. It’s designed to help you manually remove food debris and plaque between teeth and gums.

Both water flossers and traditional floss have their benefits. These include:

Pros of water flossers

  • Removes more plaque between your teeth and along the gum line
  • Massages your gums, which can improve oral health by increasing circulation
  • Don’t hurt your gums
  • Makes it easy to clean between braces, implants, and bridges
  • Convenient
  • Cleans between your teeth very quickly
  • Ideal for people with arthritis or limited mobility (dexterity)

Pros of string floss

  • Cost-effective (if you’re a consistent flosser). Water flossers are more expensive than traditional string floss, ranging from $35 to over $100. A $1 to $5 purchase of string floss can last months.
  • Enables you to clean each tooth in an up-and-down motion, moving the floss between the teeth.

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

How to Use a Water Flosser

Using a water flosser is a straightforward process:

  1. Fill the reservoir with warm water
  2. Press down firmly on the device’s base
  3. Choose a tip and click it into the handle
  4. Start with the lowest pressure setting and then place the tip into your mouth while leaning over the sink, so you don’t get water everywhere
  5. Turn the unit on and close your mouth just enough to prevent water splashes
  6. Let the water flow from your mouth into the sink below
  7. Aim the tip at your gum line
  8. When complete, turn the device off and press the “eject” button to remove the tip


Water flossers and traditional floss are effective methods of removing plaque and food debris between teeth. However, water flossers may offer more benefits than traditional flossing.

Various options are available, and our recommendations can help you find the right product for your oral health needs. Ultimately, you should consult a dentist to determine the best method and product for you.
