Cordless Water Flossers

Best Water Flossers For: Portability, small bathrooms, and cordless convenience.

Water Flossers may be something you’ve never heard of, but they’re amazing for keeping your teeth clean in a way that’s gentle and effective. They’re designed to replace the need for flossing with a thread – which, if you’ve been using normal dental floss, is great for your teeth and saves a lot of plastic going to landfill.

Because brushing isn’t usually able to get into the crevices between your teeth, flossing is essential for a good dental maintenance routine. What’s more, water flossers are much easier to use than thread flossers and let you more effectively clean to prevent gum disease, tooth decay, and bleeding gums.

They’re also great for cleaning between braces and dentures!

Our cordless water flossers take the benefits of water flossing and make them portable.

Cordless vs. Countertop Water Flossers

Compared to countertop water flossers, cordless models have the main benefit of ease. They trade off for slightly lower water pressure, but the added benefit of portability is a significant benefit to those with impaired mobility or lack of bathroom space.

The key differences between Cordless & Countertop Water Flossers is:

Cordless Water Flossers

  • Smaller water reservoir
  • Slightly lower overall water pressure
  • Easily portable – lightweight
  • Compact – so easily storable

Countertop Water Flossers

  • Large water reservoir
  • Higher overall water pressure
  • Not easily portable
  • Take up room

Whether you get a cordless or countertop flosser, there’s no particular type that’s always best: what’s best is what suits your particular needs.
