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 at least as effective as traditional dental floss, and some studies have found them to be even more effective.1, 2 Because they’re less invasive than string floss, water flossers may be ideal for people with dental implants.2, 3

Types of Water Flossers

  • 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.

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 vs. Traditional Floss 

Unlike regular floss, water flossers use high-pressure water to remove plaque and food particles between teeth. They also provide some additional benefits over traditional dental floss. For example, they offer a deeper cleaning with water, jet tips, and different cleaning modes. 

These 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 and gum line and keeps your entire mouth fresh.

Because water flossers are more convenient than string floss, they may also encourage you to floss more than you otherwise would. This would be a further benefit to your oral hygiene.

Pros of water flossers

  • They remove more plaque between your teeth and along the gum line
  • They massage your gums, which can improve oral health by increasing circulation
  • They do not hurt your gums
  • 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)

Pros of string floss

  • It is 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.
  • Flossing manually 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.
