Waterpik vs Flossing

The Importance of Flossing

Poor oral hygiene can lead to cavities, tooth loss, and gum disease. With time, gum disease can adversely affect heart health. 

The bacteria that cause gum disease can also enter your bloodstream and affect a fetus. This has been linked to premature and low birth weight of babies in pregnant women.

Brushing your teeth twice a day is essential. However, regular brushing doesn't always clean food particles, plaque, and bacteria between teeth. Toothbrush bristles are not small enough to clean between these tight spaces.

Interdental cleaning, such as flossing, is essential to maintain good oral health. There are two options for interdental cleaning: dental floss or a water flosser.

What are Waterpik Water Flossers?

Waterpik is the most popular brand of water flossers. Water flossers use a pressurized stream of pulsating water to clean between your teeth and under your gum line.

Waterpiks can help reduce bleeding and gum disease.

A Waterpik should not be used as a substitute for brushing. It is a floss replacement that helps reduce bacteria and keep your teeth and gums healthy.

You may prefer to use a Waterpik instead of flossing if you:

  • Struggle to floss daily
  • Wear braces
  • Have non-removable bridgework
  • Have crowns
  • Have dental implants
  • Have arthritis or poor mobility

Scientific studies have shown that water flossers are just as effective, or more effective than string floss at removing plaque.

How to Use a Waterpik Water Flosser Correctly 

There are a few easy steps to follow in order to use a Waterpik Water Flosser correctly: 

  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

Pros of Waterpik Water Flossers

Using a Waterpik flosser can help treat hard-to-reach areas of the mouth, tightly spaced teeth, and periodontal pockets that may result from early gum disease.

Waterpik flossers can also help keep your breath fresher for longer. Additionally, Waterpiks are simple to use. 

Cons of Waterpik Water Flossers

The main drawback of Waterpiks are their cost. They range in price from about $50 to $200.

Some people report that water flossers can be messy, and take some time to get used to.

What is Traditional Dental Floss? 

Dental floss use goes back as far as prehistoric times. Dental flossing was first recommended by a dentist named Levi Spear Parmly in 1819. Floss was officially patented 55 years later by Asahel M. Shurtleff.

Today, floss is available as rolls of string or pre-cut in plastic holders called dental picks. Traditional dental floss is available in flavored varieties and as waxed or unwaxed strands.

Pros of Dental Floss

String floss is significantly cheaper than water flossers. It typically costs $5-$10 for several yards, which will last months.

String floss gives you plenty of control. Flossing manually enables you to clean each tooth in an up and down motion, moving the floss between the teeth.

Cons of Dental Floss

Some people may not be able to treat specific areas of the mouth when using string floss. You may also have a challenging time reaching between teeth that are very close together.

If you floss too far down below the gum line or too aggressively, your gums may bleed.

Waterpik vs. Flossing: Which is Better?

Further research is needed to answer this question. However, scientific studies agree that water flossers are at least as effective as traditional floss, and may be more effective at removing plaque.

One study from 2013 found that water flossers were significantly more effective at removing plaque. Another study from 2021 found that water flossers and floss were equally efficient at removing plaque.

So what does this mean?

The best dental hygiene method is one you will stick to. If you struggle to maintain a daily habit of flossing, a Waterpik may help you change your habits.

The American Dental Association (ADA) recommends brushing twice a day and cleaning between the teeth once a day with floss or a water flosser.
