The Best Waterpik Water Flosser: Reviews & Buyers Guide

One of the world's most under used and most avoided inventions, dental floss, was created around 200 years ago. In an article for entitled "Water Flosser Can Address the Futility of Floss", registered dental hygienist Terri Tilliss writes that two-thirds of dental patients behave as if dental floss has gone away. To quote her:

"They generally do not think about it, they do not use it, and they do not care that they do not use it except possibly during the regular scolding that they expect at dental visits."

She adds that, "A survey of health professionals, including dentists, found that the majority admitted to not flossing daily." So, even dentists who preach dental care to their patients don't necessarily practice what they preach. Tilliss regards it as counterproductive to continue to recommend a product that people don't like and won't use when there is an alternative that people are more likely to use. So, what invention does Tilliss recommend? The oral irrigator or water flosser, the 1962 invention that became the start of the company now known as Waterpik.

What is a Waterpik?

A Waterpik flosser is a countertop or handheld device that directs a concentrated stream of water onto the surface of the teeth and gums and into the crevices between the teeth and the pockets between the teeth and the gums. These flossers are designed to remove food particles, plaque, and subgingival bacteria while also massaging the gums. Waterpik has many models on the market designed to suit various needs.

How Does a Waterpik Work?

Countertop flossers plug into an outlet, while cordless ones are powered by either rechargeable or disposable batteries.

Power goes to a motor and pump that pumps the water from a water reservoir to the tip. In countertop models, the reservoir is contained in the base, and the liquid passes through a tube to the flossing tip. These reservoirs can hold up to 35 ounces of water for 90+ seconds of flossing. In cordless models the reservoir is contained in the handle and holds 5 ounces to 7 ounces of H2O for 15 to 45 seconds of flossing.

The exact flossing time provided depends on the water pressure settings you choose, but you can refill the reservoir for more time. The recommended time is 60 seconds of flossing daily, and some water flossers have timers so that you know you have thoroughly flossed your teeth and massaged your gums.

To use your waterpik, fill the reservoir with lukewarm water or a 1:1 solution of H2O and mouthwash. Place the reservoir on the base and make sure that it’s secure. Select the tip, and press it into the handle firmly. The first time you use your water flosser, turn the water pressure to high, point the tip into the sink, turn on the water, wait until the water begins to flow, and then turn the flosser off.

Lean over the sink, adjust the water pressure to low for your first use, and place the tip in your mouth with your lips closed to prevent the water from splashing. Turn the unit on and move the tip along your gums while allowing the water to drain through your lips into the sink.

Floss your teeth, starting at the back, while holding the flosser tip at a 90° angle. Aim just above the gum line. Pause briefly at the crevices between your teeth. Turn the flosser off when you’re done and either eject the tip with the eject button or pull it from the handle. Finally, brush your teeth.

Pros and Cons of a Waterpik


  • Waterpik water flossers provide a unique combination of water pressure and pulsation that removes up to 99.9 percent of plaque.
  • Reduced bleeding gums by 44 percent more and gingivitis by 41 percent more than those who did not use a water flosser in a three month study of diabetics.
  • Reduced plaque three times better than those who brushed and flossed and five times better than those who only brushed for study participants with braces aged 11 through 17.


  • Require that flossing tips be replaced every three to six months
  • Cost more than using dental floss when replacement tips are averaged into costs.
  • According to some customer reviews, some models have had leaking issues.

Choosing a Waterpik -- Buying Tips

Cordless, Portable Waterpiks

The motor, pump, batteries, and reservoir for portable Waterpiks are all in the handle, so the handles of these flossers are bulky. You can control the water pressure, but your choices will be more limited than they would be on a countertop waterpik.

Some allow you to rotate the flossing tip 360° to reach every part of your mouth, and some have a switch that allows you to change from a steady stream of water for flossing to a pulsating one for massaging your gums. In general, though, these are less expensive, basic water flossers, but they do take up only a minimal amount of space in luggage or in a bathroom with little countertop space.

Rechargeable batteries generally need recharging every two weeks, but portable flossers are designed for travel and can be charged using either U.S. or international voltages. If you would rather not worry about complying with travel restrictions on lithium ion batteries, you might prefer a portable Waterpik that uses disposable batteries.

Corded, Countertop Waterpiks

The base of a countertop flosser includes the reservoir, the motor, the pump, and a holder for the flossing handle. It may have storage space for your most used tips. The handles for countertop flossers are much more slender than those of portable water flossers, but you do have to contend with manipulating the tube. As with portable flossers, the on/off switch is in the handle. The base varies in size depending on the size of the reservoir.

Reservoirs may contain 15 ounces, 22 ounces, or 35 ounces of water. The 15 ounce reservoir provides 60+ seconds of flossing while a 22 ounce to 35 ounce reservoir provides 60+ to 90+ seconds of flossing. You will have more choices when it comes to water pressure settings than you will find on a portable model, and most countertop flossers come with two color-coded, general purpose flossing tips. Basic countertop models may offer a tip ejector button, but with some you will still need to pull the tip from the handle by hand.

Advanced Features

Advanced features include a switch in the handle that allows you to pause the water flow as well as one that allows you to switch from a steady stream of water for flossing your teeth to a pulsating stream for massaging your gums. Advanced models also may include a control that allows you to rotate the flossing tip to more easily reach all areas of your mouth. Some models offer a timer/pacer feature.

The pacer automatically pauses the water flow after 30 seconds to remind you to switch to the other side of your mouth. The timer automatically pauses the water after 60 seconds to let you know that you have completed the recommended time for water flossing. However, the flosser does not shut off until you hit the off button.

Advanced flossers come with two or more general purpose flossing tips plus some special purpose tips. The special purpose tips could include an orthodontic tip for cleaning implants or around other appliances, a tip for removing subgingival bacteria and food particles from the pocket between the tooth and the gum, a plaque removal tip, a tongue cleaning tip, and/or a toothbrush tip.
