Water flossers: The 8 best water flossers of 2023

A water flosser is a small powered device that uses pressure to direct a spray of water over and between your teeth, blasting away plaque and other buildups that can result in inflammation, gum disease, and cavities. Plaque can be effectively removed from your gums and the crevices between your teeth by flossing once a day. A water flosser can help you floss better by eliminating more bacteria-causing plaque than string floss alone if you have gingivitis, wear braces or aligners, or simply struggle with the fine motor control required to weave dental floss between your teeth.

Best Water Flosser Overall: Aquasonic Aqua Flosser


Aquasonic Aqua Flosser
Aquasonic Aqua Flosser – Best Water Flossers

Why We Like It: The cordless design is effective and comfy to use, and it is considerably less expensive than products with the Waterpik brand.

It’s Worth Noting: If you want a water flosser with more sophisticated settings, keep reading because this isn’t the coolest one available.

Our tester was thrilled by this Aquasonic Aqua Flosser’s straightforward on/off switch and simplicity of adjusting settings while in use, making it our top pick overall. This is due to the fact that ergonomics—how easy it is to handle and use the water flosser—are crucial, and this Aquasonic model shines in simply one. It’s well-designed, with a decent handle shape, as our tester noted.

Between good and great water flossers, there are key differences in pressure settings and reservoir capacity. This flosser only has three settings, which is less than some of the more expensive alternatives on our list, but they work well and are effective, so we gave it a rating of 4.5 out of 5 for settings. One tester in particular loved the pulse mode, stating it was very good at cleaning between her teeth.

You’ll need a flosser with a sizable enough tank that won’t need to be refilled or cut your session short before you’ve reached every crevice of your mouth if you want to receive a thorough clean. The Aquasonic’s tank size surprised our tester in part because it has a cordless design, whereas corded models often compromise tank size in order to be portable. Also, our tester discovered that filling the tank was simple.

It’s challenging to find a powerful cordless water flosser with a tank big enough to last the duration of a cleaning session. And we don’t believe you can find anything else for less money.

Best Budget: H2ofloss Water Flosser Portable Dental Oral Irrigator

H2ofloss Water Flosser Portable Dental Oral Irrigator
H2ofloss Water Flosser Portable Dental Oral Irrigator – Best Water Flossers

Why We Like It: Our budget selection features an incredible variety of settings and unique tips for a product with such a low price.

It’s Worth Noting: The high pressure settings could be too harsh for certain individuals.

Our tester was shocked that this flosser didn’t cost more given how versatile and functional it is, therefore we chose the H2ofloss Water Flosser Portable as our best value pick. Unlike some less expensive flossers, this one contains six tips, including two jet tips, an orthodontic tip, a tongue cleaner, a periodontal tip, and a toothbrush tip. It also has five pressure levels that go from low to extremely high.

The H2ofloss received a grade of 5 for ease of use even though it didn’t come with a detailed set of step-by-step instructions. It features a simple and functional design.

The flosser cleaned teeth well and has a remarkable amount of water storage for a portable device. The device left our testers’ mouths feeling clean, but they had trouble finding the proper intensity—the higher settings were a little too intense and splashed more water all over the place.

Overall, this is a cheap choice that is excellent for novices. Although it doesn’t come with many supplemental parts or accessories, the range of pressure settings and nozzle choices puts this budget-friendly option above its rivals.

Best Waterpik: Waterpik Aquarius Water Flosser

Waterpik Aquarius Water Flosser
Waterpik Aquarius Water Flosser – Best Water Flossers

Why We Like It: The Aquarius is a reliable countertop flosser that won’t make you feel rushed. It has a sizable reservoir.

It’s Worth Noting: The reservoir to flosser cord is noticeably short.

In our testing, we found the Waterpik Aquarius to be a reliable flosser that was neither extremely sophisticated nor unduly simple, with a long-lasting water tank that allowed us to thoroughly clean our teeth without feeling rushed. It earned a 5 for effectiveness since, even when our tester utilized the lower, softer settings, it left our teeth immaculately clean.

The fact that water flossers can be challenging to use with braces, especially for young children who could have trouble using a larger-size flosser, is one of the most challenging parts of doing so. The Aquarius, according to our tester, has a smaller handle that would be perfect for kids.

The Aquarius was given a 5 for settings as well. It contains a timer that warns you after 30 and 60 seconds of use, ten pressure settings that can be adjusted on the flosser base, and seven various nozzle tips (or family members).

The only issue our tester experienced was that the wire connecting the flosser to the base was too short, making it a little more challenging to use the handle. If you want a countertop water flosser with a large reservoir and don’t mind flossing next to the sink, the Aquarius is a standout Waterpik.

Best Cordless: Waterpik Rechargeable Cordless Plus Water Flosser

Waterpik Rechargeable Cordless Plus Water Flosser
Waterpik Rechargeable Cordless Plus Water Flosser – Best Water Flossers

Why We Like It: It has a straightforward, minimalist design that is perfect for novices who wish to add a water flosser to their oral hygiene regimen.

It’s Worth Noting: This flosser is a basic flosser that does the job without any unique or noteworthy features.

Because of its lightweight, minimalist design and positive comments from both of our testers, the Waterpik Cordless Advanced is our pick for the best cordless. The simplest way to test out a water flosser without committing to a more intricate model is with a basic cordless alternative if you’ve never used one before and are unsure of whether it’s suited for you.

With our testers noting that the reservoir was easy to fill and that the water lasted far longer than the 45 seconds specified on the package, this Waterpik got a 5 for simplicity of use. They also remarked how easy the device was to set up and utilize.

With only three pressure levels, the Waterpik Cordless Advanced, on the other hand, does not offer a highly personalised experience (and it costs more than some models with 10 settings, like the Turewell). It did a decent job of cleaning our teeth; one tester said it did so in about a minute, while another observed some residue and felt like there was a touch too much water in their mouth.

The Waterpik Cordless Advanced is a great option for those who are new to using a water flosser because it is lightweight and ergonomic in general. We advise the Waterpik Cordless Advanced for first-time users and anyone worried that string floss alone isn’t adding enough value to their oral care regimen, even though it might be too easy for some and one of our testers felt it wasn’t worth the price until on sale.

Best Portable: MySmile Portable Oral Irrigator X

MySmile Portable Oral Irrigator X
MySmile Portable Oral Irrigator X

Why We Like It: The MySmile, which has the largest reservoir of any water flosser in our test, does not compromise reservoir size for portability like other models might.

It’s Worth Noting: To find the setting that works best for you, you might need to experiment with different settings.

Our tester discovered the MySmile to be a particularly user-friendly experience because of its digital appearance and travel-friendly capabilities. You receive a water flosser that is perfect for packing in a backpack or luggage and carrying with you wherever you go in addition to a complimentary travel pouch.

The MySmile boasts the largest 350 milliliter tank of any cordless flosser we examined, despite being battery-powered and small. Because of this, the flosser will last longer before needing to be refilled, but it will be roughly the same size and price as the other flossers on this list.

The MySmile’s digital features made operation considerably simpler during testing; our tester could quickly see the water temperature, pressure settings, and battery life, which elevated the flosser’s aesthetic and practical usability above some of the others we examined. Also, we enjoyed the assortment of nozzle attachments, especially the one with the bristle brush; our tester gave the MySmile a 5 for effectiveness because it seemed like brushing and flossing at the same teeth.

The MySmile struggled in the area of use; our tester scored it a 4 since it was a bit difficult to change the pressure settings and she wasn’t sure whether to use the “soft” or “kid” setting for the lowest pressure. The fact that MySmile gave us the impression of being “totally clean” and that the digital design made our testing experience better was unaffected by this, though.

Best Electric Toothbrush-Water Flosser Combo: Waterpik Sonic-Fusion 2.0 Professional Flossing Toothbrush

Waterpik Sonic-Fusion 2.0 Professional Flossing Toothbrush
Waterpik Sonic-Fusion 2.0 Professional Flossing Toothbrush

Why We Like It: You can brush and water floss from the same base with this dual-purpose Waterpik gadget, eliminating the need to maintain two separate devices on your sink.

It’s Worth Noting: This model’s brush-flosser setup leaves it lacking in nozzle variation.

The Sonic Fusion 2.0 is the best electric toothbrush-water flosser combination because it combines a toothbrush and a flosser into one device that allows you to brush and floss at the same time. Our tester also like how simple it was to change settings.

It is unique among countertop flossing devices for the unit to have a large reservoir while yet being small. It received a score of 4 out of 5 stars from our tester, who called it “sleek” and said it seemed to be made to look well on a bathroom sink.

The Fusion earns a 4 for efficiency and usability in addition to its appealing appearance. Our test subjects felt that the Sonic Fusion instantly cleaned their mouths, as if they had recently had their teeth professionally washed, whether they used the Pik flosser or the toothbrush (or both).

Also, our tester said the interface was easy to use, with a dial to adjust the pressure setting to particular levels and more practical handheld buttons to change function settings when moving from brushing to flossing. The Sonic Fusion effectively serves both of its purposes and saves time if you don’t have the time to fiddle around with a completely other oral care tool.

Price at time of publication: $200

  • Dimensions: 10.9 x 5.25 x 6 inches
  • Reservoir Size: 16 oz
  • Pressure Settings: 10
  • Attachment Nozzles: 2
  • Extra Features: built-in timer, travel case, recharge indicator

Best Oscillating Nozzle: Spotlight Oral Care Water Flosser

Spotlight Oral Care Water Flosser
Spotlight Oral Care Water Flosser

Why We Like It: Anyone who is uncomfortable with the thought of water flossing will find the Spotlight to be a wonderful option because the oscillating motion makes flossing simpler.

It’s Worth Noting: When compared to other products with equivalent functionality, the Spotlight is pricey unless you need a lot of persuasion to floss.

You might not think that selecting a water flosser with an oscillating head is a big issue, but our tester noted how useful (and simple!) it was to utilize our pick for the best oscillating nozzle due to this minor but crucial function. Our tester found that the Spotlight Oral Care Water Flosser offers a more complete clean with significantly less effort since it can guide more water around and in between your teeth and gums than other flossers.

The Spotlight did somewhat worse than expected in other areas, as our tester found that, aside from the oscillating nozzle, there isn’t much about this flosser that makes it worth its premium price. The reservoir is somewhat small while the power button is slow to respond and changes color to show the state you’re in.

Nonetheless, the Spotlight gets a spot on our list because of how effortless it is to blast off sticky food fragments thanks to the oscillating head. Also, our tester observed that the nozzle is quite small, making it a suitable option for anyone who has orthodontics (especially because the oscillation support water flosser to wash away plaque in a short time).

Best with Additional Nozzles: Turewell Water Dental Flosser

Turewell Water Dental Flosser
Turewell Water Dental Flosser

Why We Like It: Due to its numerous nozzle attachments and pressure levels that can be adjusted for individuals with sensitive gums, this water flosser stands out from the competition.

It’s Worth Noting: You’ll need some time and skills if you want to use a variety of nozzles because attaching them can be challenging.

Yes, the Turewell water flosser won our award for best with extra nozzles because it has three jet nozzles and five issue-specific nozzles, but more importantly, our tester found that the flosser head itself was small enough to access difficult-to-reach areas. As a result, you can use all those fancy nozzle heads in every part of your mouth, maximizing your oral hygiene routine.

In fact, the Turewell was compared by our tester to their own personal Waterpik device at home, which says a lot about the Turewell’s all-around value. The unit’s ease of use rating was reduced to 4 by our tester because switching out the various nozzles involves some effort. The device’s pressure settings, however, receive a 5; according to our tester, the fact that it simply had an on/off button and a pressure setting dial made it easy to operate.

Our tester said, “The pressure dial was able to focus in on exact pressure settings that most other wet flossers are unable to.” As typical flosser pressure levels may be too harsh for those with sensitive teeth and gums, like our tester, the Turewell is a good option. If you’re looking for a less expensive alternative to an expensive water flosser and a thorough clean that’s mild enough for sensitive teeth and gums, the Turewell has the ideal combination of settings and nozzles to satisfy your demands.

Price at time of publication: $50

  • Dimensions: 8.7 x 6.2 x 5.1 inches
  • Reservoir Size: 600 ml
  • Pressure Settings: 10
  • Attachment Nozzles: 8
  • Extra Features: none

More Water Flossers to Consider

These water flossers were also put to the test, but we ultimately decided not to suggest them. In terms of technology, features, and functionality, they failed our test:

  • Waterpik Nano Plus: This flosser has a huge reservoir and is light and portable, according to our tester, in terms of, we prefer some other Waterpik alternatives.
  • Waterpik Cordless Express: This powerful flosser can practically be used straight away. It has two settings, and even the lowest setting, according to our testers, is still fairly effective, is suitable for someone who needs a high level of intensity.
  • Waterpik ION Professional: Although the Ion is attractive, compact, and easy to use, we weren’t as thrilled with the quality of its construction. Our tester had trouble putting the nozzle attachment back together after it detached while in use.
  • Waterpik Cordless Pearl: We found that the Pearl is more appropriate for travel than daily use. According to our tester, it was difficult to use around the front teeth and the attachment had to be reinserted multiple times.
