Are waterpiks better than flossing?

Water flossers have become a popular alternative to string floss, but when it comes to keeping your teeth and gums healthy, which tool does a better job?

Are water flossers better than regular floss?

Most of us know that brushing isn’t enough to keep our mouths fully clean. Brushing alone only removes about 60% of the plaque in your mouth, which is why dentists always recommend flossing.

While most people still use traditional string floss, water flossers (or Waterpiks) have become a popular alternative. When it comes to keeping your teeth and gums healthy, which tool actually does a better job - regular floss or a water flosser?

What are water flossers?

Water flossers aren’t actually new — the first versions were introduced way back in 1962. These devices look a little like an electric toothbrush but use a pressurised stream of water to remove plaque and food debris from your teeth. They’re made up of a water reservoir (a fillable body) and a detachable nozzle.

Water flossers usually cost around $100, although many models are more expensive. Just like your toothbrush, you’ll need to change the water flosser head every six months, or every three months if your model has bristles.

Why are water flossers popular?

Part of their popularity comes from how easy they are to use. All you need to do is switch your water flosser on, aim it at your gum line, and move it around your mouth.

They’re also a great tool for people with braces. The pressurised stream makes it easy to clean between brackets and wires—areas that string floss simply can’t reach.

Many people find water flossers much gentler on their gums than traditional floss. If you have gingivitis or sensitive gums, string floss can feel a little uncomfortable at first.

Thanks to their design, water flossers can also make it easier to reach hard-to-access areas. The thin tip can travel all the way back to your rear molars, which are often difficult to reach with traditional floss.

Are water flossers better for gum health?

Yes and no. Studies have found that water flossers can be up to 50% more effective at reducing gingivitis than string floss, but dentists also warn that they may not remove all plaque. Here are the pros and cons:

 Pros

  • Easier to use, which can lead to more regular flossing
  • Better access to hard-to-reach areas
  • Removes food and plaque from most places

 Cons

  • Not as effective at removing stubborn plaque
  • More expensive than regular floss
  • Incorrect use can be messy
  • The water reservoir needs regular cleaning

How is traditional floss better than a water flosser?

More control

Traditional floss gives you more control than a water flosser, making it easier to remove stubborn plaque.

 Cheaper

Dental floss costs around $3–$5 and lasts a long time. Water flossers typically cost $90–$300 and require replacement heads two to four times per year.

 No cleaning required

Water flossers can accumulate mineral deposits in their reservoirs, meaning you’ll need to clean them at least once a month.

How is a water flosser better than traditional floss?

Ease of use

Water flossers are an excellent option for people with dexterity issues.

 Access to hard-to-reach places

They can easily target the back of your mouth and other tricky areas.

Which should you choose: traditional floss or a water flosser?

It’s up to you. Both traditional floss and water flossers can reduce gingivitis and keep your mouth free from plaque and tartar. The choice is less about which tool is “better” and more about which one you’ll use consistently. If you switch to a water flosser, it’s a good idea to keep some string floss on hand for times when you need more precision.
