The 8 best water flossers of 2023:
Water flossers are small powered devices that use pressure to direct a stream of water around and between your teeth, blasting away plaque and other buildups that cause inflammation, gum disease, and cavities. Flossing once a day is an effective way to remove plaque from your gums and between your teeth’s nooks and crannies. If you have gingivitis, wear braces or aligners, or simply have difficulty with the fine motor manipulation of weaving dental floss between your teeth, a water flosser can improve your flossing by removing more bacteria-causing plaque than string floss alone.
The 8 best water flossers of 2023 – Best Overall: Aquasonic Aqua Flosser

Why We Like It: The cordless design is efficient and comfortable to use—and it costs a fraction of what a brand name like Waterpik would.
It’s Worth Noting: This isn’t the coolest water flosser on the market, so if you want something with more advanced settings, keep reading.
This Aquasonic Aqua Flosser is our favorite overall because it impressed our tester with its simple on-off switch and ease of switching between settings while in use. That’s because ergonomics—how comfortable the water flosser is to hold and operate—are so important, and this Aquasonic model excels in just one area. Our tester commented on how well-designed it is, with a nice shape to the handle.
Pressure settings and reservoir size are important factors in distinguishing between good and great water flossers. We gave this flosser a 4.5 out of 5 stars for settings because it only has three settings (fewer than some of the more expensive options on our list), but they are effective and do the job. The pulse mode, in particular, was a tester favorite, with one saying it did an excellent job of removing gunk from between her teeth.
To get a thorough clean, you’ll need a flosser with a large enough tank that won’t need to be refilled or cut your session short before you’ve reached every nook and cranny of your mouth. The tank size on the Aquasonic impressed our tester, primarily because it is a cordless design—typically, cordless models sacrifice tank size in order to be compact enough to handle. Furthermore, our tester found the tank to be simple to fill.
Finding a high-powered cordless water flosser with a tank large enough to last through an entire cleaning session is difficult. And we don’t think you can do better at this price.

The 8 best water flossers of 2023 – Best Budget: H2ofloss Water Flosser Portable Dental Oral Irrigator
Why We Like It: For such a low price, our budget pick has an impressive number of settings and different tips.
It’s Worth Noting: Some people may find the high pressure modes too intense.
The H2ofloss Water Flosser Portable was chosen as our best budget pick because our tester was surprised that this flosser didn’t cost more given how versatile and functional it is. Unlike some less expensive flossers, this one has five pressure settings ranging from low to super high and six tips: two jet tips, an orthodontic tip, a tongue cleaner, a periodontal tip, and a toothbrush tip.
Even without a clear set of step-by-step instructions, our tester found the H2ofloss to be intuitive and easy to figure out; it has a clean and practical design, earning a rating of 5 for ease of use.
The flosser was also effective at cleaning teeth and held a surprising amount of water for a portable unit. Our testers’ mouths felt clean after using the device, but they struggled to find the right intensity—the higher settings were a little too strong and splashed excess water everywhere.
Overall, this is a low-cost option that would be ideal for beginners. It doesn’t come with many extraneous pieces or accessories, but the variety of pressure settings and nozzle options elevates this low-cost option above its competitors.

The 8 best water flossers of 2023 – Best Waterpik: Waterpik Aquarius Water Flosser
Why We Like It: The Aquarius is a solid countertop flosser with a large reservoir that won’t leave you feeling rushed.
It’s Worth Noting: The flosser’s cord to the reservoir is noticeably short.
During our testing, we discovered the Waterpik Aquarius to be a solid flosser: not overly complicated or overly simple, with a long-lasting water tank that allowed us to get all the gunk out of our teeth without feeling rushed. It received a 5 for effectiveness because it left our teeth spotlessly clean, even when our tester used the lower, gentler settings.
One of the most difficult aspects of using a water flosser with braces is that they can be difficult to manipulate, especially for children who may struggle with a larger-size flosser. However, our tester noted that the Aquarius has a smaller handle that would be ideal for children.
In terms of settings, the Aquarius received a 5 as well. It has ten pressure settings that are adjustable on the flosser base, a timer that alerts you after 30 and 60 seconds of use, and seven different nozzle tips (or family members).
The short cord connecting the flosser to the base was the only complaint our tester had; it made using the handle a little more difficult, and they wished it was longer. The Aquarius is a standout Waterpik if you want a countertop water flosser with a long-lasting reservoir and don’t mind flossing close to the sink.

The 8 best water flossers of 2023 – Best Cordless: Waterpik Rechargeable Cordless Plus Water Flosser
Why We Like It: It has a simple and minimalist design that is ideal for beginners who want to incorporate a water flosser into their oral care routine.
It’s Worth Noting: There are no special or noteworthy features on this flosser; it is a basic flosser that simply gets the job done.
The Waterpik Cordless Advanced is our choice for best cordless because both of our testers mentioned how ideal it would be for beginners, owing to its lightweight, minimalist design. If you’ve never used a water flosser before and aren’t sure if it’s right for you, a basic cordless option is the best way to try one out without committing to a more complicated unit.
This Waterpik received a 5 for ease of use, with our testers remarking that the reservoir was simple to fill and that the water lasted much longer than the 45 seconds indicated on the package. They also mentioned how simple it was to set up and use the product.
The Waterpik Cordless Advanced, on the other hand, does not provide a highly customized experience with only three pressure settings (and it costs more than some models with 10 settings, like the Turewell). It did a good job cleaning our teeth, with one tester reporting that it cleaned their teeth thoroughly in about a minute, while another noticed some residue and thought there was a little too much water in their mouth.
Overall, the Waterpik Cordless Advanced is lightweight and ergonomic, making it an excellent choice for those who are new to using a water flosser. While it may be too simple for some, and one of our testers felt it wasn’t worth the price unless on sale, we recommend the Waterpik Cordless Advanced for first-time users and anyone concerned that string floss alone isn’t providing enough benefit to their oral care routine.

The 8 best water flossers of 2023 – Best Portable: MySmile Portable Oral Irrigator X
Why We Like It: Other models may sacrifice reservoir size for portability, but not the MySmile, which has the largest reservoir of any water flosser in our test.
It’s Worth Noting: You may need to experiment with the settings until you find the one that works best for you.
Because of the combination of its digital design and travel-friendly features, our tester found the MySmile to be a uniquely user-friendly experience. With the addition of a free travel pouch, you get a water flosser that’s ideal for storing in a bag or suitcase and taking with you wherever you go.
Despite being battery-powered and compact, the MySmile has the largest tank of any cordless flosser we tested, measuring 350 milliliters. That means you’ll get more use out of the flosser before it needs to be refilled, but it’ll be about the same size and cost as the other flossers on this list.
During testing, we appreciated the MySmile’s digital features, which made operation much easier: our tester could see the water temperature, pressure settings, and battery life at a glance, elevating the flosser’s appearance and actual usage above some others we tried. We also liked the variety of nozzle attachments, particularly the one with the bristle brush; our tester said it felt like brushing and flossing at the same time, earning the MySmile a 5 for effectiveness.
One area where the MySmile fell short was ease of use; our tester gave it a 4 because changing the pressure settings was a little confusing and she wasn’t sure whether to use the “soft” or “child” setting for the lowest pressure. But this had no effect on how well MySmile worked—it gave us that “total clean” feeling, and the digital design truly enhanced our testing experience.

The 8 best water flossers of 2023 – Best Electric Toothbrush-Water Flosser Combo: Waterpik Sonic-Fusion 2.0 Professional Flossing Toothbrush
Why We Like It: With this dual-purpose Waterpik unit, you don’t need to keep two separate devices on your sink—you can brush and water floss from the same base.
It’s Worth Noting: Because of the brush-flosser combination, this model lacks nozzle variety.
The Sonic Fusion 2.0, as an electric toothbrush and flosser in one, allows you to brush, floss, or do both at the same time—and our tester found it super easy to switch between settings, making it a clear choice for best electric toothbrush-water flosser combo.
The unit has a large reservoir while remaining compact, which is unusual in the world of countertop flossing units. In fact, our tester described it as “sleek” and noted that it appeared to be designed to look good on a bathroom sink, giving it a rating of 4 out of 5 stars.
The Fusion not only looks good, but it also gets a 4 for effectiveness and ease of use. Whether using the pik flosser or the toothbrush (or both), our testers thought the Sonic Fusion left their mouth feeling instantly clean, as if they had just had their teeth professionally scrubbed.
Our tester also found the interface simple to navigate, with a dial to control the pressure setting to specific levels and more convenient handheld-based controls to adjust function settings when switching from brushing to flossing. If you don’t have time to mess around with an entirely separate oral care device, the Sonic Fusion performs both of its functions well and saves time.
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
The 8 best water flossers of 2023 – Best Oscillating Nozzle: Spotlight Oral Care Water Flosser
Why We Like It: The oscillating feature makes flossing easier, making the Spotlight a good choice for anyone who is put off by the idea of water flossing.
It’s Worth Noting: Unless you need a lot of convincing to floss, the Spotlight is expensive when compared to other products with comparable features.
You might not think that finding a water flosser with an oscillating head is a big deal, but our tester remarked on how effective (and easy!) it was to use our pick for the best oscillating nozzle because of this small but important feature. The Spotlight Oral Care Water Flosser is able to direct more water around and in between your teeth and gums than other flossers, providing a more thorough clean with far less effort, according to our tester.
However, the Spotlight underperformed slightly in other areas: our tester discovered that, aside from the oscillating nozzle, there isn’t anything special about this flosser that would justify its higher price. The power button is slow to respond, but it changes color to indicate the mode you’re in; in the meantime, the reservoir is a little small.
Nonetheless, the Spotlight’s total ease of blasting out gunky bits of food thanks to the oscillating head earns it a spot on our list. Furthermore, our tester noted that the nozzle is on the small side, making it a good choice for anyone with orthodontics (especially when you combine that with the fact that the oscillation might help a reluctant water flosser remove more plaque in a shorter period of time).

The 8 best water flossers of 2023 – Best with Additional Nozzles: Turewell Water Dental Flosser
Why We Like It: This water flosser stands out from the crowd thanks to a variety of nozzle attachments and adjustable pressure settings for people with sensitive gums.
It’s Worth Noting: Attaching the nozzles can be difficult, so if you plan on using a variety, you’ll need some skill and patience.
Yes, the Turewell water flosser won our award for best with extra nozzles because it comes with three jet nozzles and five issue-specific nozzles, but more importantly, our tester discovered that the flosser head itself was small enough to access hard-to-reach areas—which means you can use all those fancy nozzle heads in every part of your mouth, maximizing your oral health routine.
In fact, our tester compared the Turewell to their own personal Waterpik unit at home, which speaks volumes about the Turewell’s overall value. According to our tester, changing out the various nozzles requires some fiddling, lowering the unit’s ease of use rating to 4. Meanwhile, the unit’s pressure settings earn a 5; our tester liked that it only had an on/off button and a pressure setting dial, making it simple and intuitive to use.
“The pressure dial was able to zero in on precise pressure settings that most other wet flossers are unable to,” our tester added. This makes the Turewell suitable for people with sensitive teeth and gums, such as our tester, who may find standard flosser pressure settings too intense. The Turewell has the right combination of settings and nozzles to meet your needs if you’re looking for a less expensive alternative to a pricey water flosser and a thorough clean that’s gentle enough for sensitive teeth and gums.

More Water Flossers to Consider
We tested these water flossers as well, but ultimately decided against including them in our list of recommendations. They failed our test in terms of technology, features, and functionality:
- Waterpik Nano Plus: Our tester thought this flosser was small and compact, with a large reservoir, but for the price, we prefer some other Waterpik options.
- Waterpik Cordless Express: This is a strong flosser that is nearly ready to use right out of the box. It has two settings, which are adequate for someone who requires a high level of intensity—our testers noted that the lowest setting is still quite potent.
- Waterpik ION Professional: The Ion is stylish, small, and simple to use, but we weren’t as impressed with its build quality. Our tester struggled to reassemble the nozzle attachment after it fell off during use.
- Waterpik Cordless Pearl: We discovered that the Pearl is better suited to travel than everyday use. It was messy to use along the front teeth, and the attachment had to be re-inserted several times, according to our tester.
