Are Water Flossers Like Waterpik the Best Way to Floss?

The water flosser was introduced as an alternative to traditional string floss in 1962. It is one of the most studied self-care devices on the market. But many people have questions about how effective it is and whether it's the best way to floss. 

Let’s take a closer look at the Waterpik water flosser and how it compares to string floss. Then you can decide if a water flosser is right for you.

What is the Waterpik flosser? 

The Waterpik is the most well-known water flosser. It’s a type of interdental cleaner. Interdental cleaners help remove trapped food and plaque from between and around your teeth. 

The Waterpik water flosser uses a tip that sprays a stream of water at your teeth and gumline. You can set this to different pressure levels. Water flossers thoroughly remove dental debris, which helps improve oral health.   

There are different types of water flossers available, and they have a range of functions. Some water flossers are a stand-alone interdental cleaner. Others combine a toothbrush, which lets you brush and floss your teeth at the same time. 

What are the pros and cons of using the Waterpik?

The Waterpik is a good alternative to traditional floss, but it’s not for everyone. There are benefits and drawbacks to using the Waterpik. Let’s start with the positives.

Water flossers decrease the likelihood of gum disease. Research has shown that the Waterpik can remove up to 99% of plaque. People who struggle to use string floss may have an easier time using a water flosser. This may be especially true for people who:

• Have manual dexterity issues (due to things like arthritis and carpal tunnel syndrome)

• Wear braces

• Have crowns, bridges, or implants

• Have periodontal disease

But water flossers like the Waterpik have some drawbacks:

• More expensive than string floss

• Messy if not used properly

• Hard to store, and takes up counter space

Are Waterpiks better than standard dental floss and brushing?

There’s limited research comparing the use of the Waterpik water flosser versus standard dental flossing by hand. Both are effective at removing plaque between and around the teeth when combined with brushing. 

One small study showed a significant benefit to using the Waterpik water flosser over string floss. The water flosser was almost 30% more effective at removing plaque from the teeth. This may be due to issues with flossing technique rather than the water flosser being a more effective product. But it’s important to note that, for some, a water flosser may be easier to use. 

How do you use a water flosser?

You can use a water flosser as part of your regular oral-care and toothbrushing routine. You can use it to floss before you brush your teeth. 

To use a water flosser, follow these six steps:

1. Fill the reservoir with warm water.

2. Choose the most comfortable water pressure setting.  

3. Before turning the device on, place the head of the flosser in your mouth.

4. Hold your head over the sink to prevent making a mess.

5. Turn it on and begin water flossing between your teeth and around your gumline.

6. Empty the water reservoir and rinse it after each use.

You can use a water flosser daily to access hard-to-reach areas that toothbrushing alone can’t clean. Using the Waterpik water flosser should not cause any pain or discomfort. Start at the lowest water-pressure setting. You can gradually increase the pressure over time as needed.
