A wet flosser (aka oral irrigator) essentially flushes your mouth with pulsating water to get rid of gunk between the teeth, clean hard-to-reach areas, and prevent bad breath. Using one of these gadgets is a great way to amp up your oral hygiene game between dentist visits. Not only will squeaky-clean teeth up your dentist chair selfie game to Brook Shields status, but they’ll also up your confidence so you can do things like remove your new wife’s garter with your pearly whites.
“A wet flosser goes in deeper below the gum line, even further than regular floss, to remove more plaque and debris,” says Rhonda Kalasho Zoumalan, DDS, one of Hollywood’s leading cosmetic dentists. “Water flossers have been proven through several studies to help reverse gum disease, minimize staining, and freshen breath.”
We tried over two dozen water flossers in the Lab, evaluating each model for ease of use, effectiveness, settings, and overall value. Our number one pick is the Aquasonic Aqua Flosser, a reasonably priced, user-friendly gadget with a conveniently cordless design. But to help you narrow down your options, we rounded up several standout designs for squeaky-clean teeth and healthy gums.
These are the best wet flossers PEOPLE Tested.
Waterpoof design
Minimal effort required
Reasonably priced
Comfortable handle
Rechargeable battery
Only has three modes
After trying 26 models in the Lab, the Aquasonic Aqua Flosser was a clear winner. It clocked perfect scores for ease of use and effectiveness, losing only half a point for settings. (It has only three modes — not a terribly low amount but not outstanding.)
Describing it as "an all-around great water flosser," our tester said it got every bit of gunk out of her teeth. She also liked how the curved handle felt in her hand, noting that it's easy to hold, direct the flow of water, and switch between the normal, soft, and pulse modes. She was particularly fond of the pulse setting, which she said did an excellent job flushing out crumbs from between her teeth. The water reservoir was easy to fill as well.
Thanks to a rechargeable lithium-ion battery, the Aqua Flosser is conveniently cordless and lasts for weeks between charges. Not only that, but the waterproof design means you can use it in the shower.
Other notable features include a built-in two-minute timer and a 360-degree rotary nozzle that makes it easy to clean hard-to-reach areas. Considering the very reasonable price tag and the fact that it comes with four replacement tips, we gave this product a perfect score for overall value. With that said, we'd recommend it to pretty much anyone in the market for a water flosser.

Has five modes
Comes with six heads
Large water reservoir
Rechargeable battery
Instruction manual isn't very thorough
Higher-pressure modes splash lots of water
H2ofloss makes a great budget pick. The brand's Cordless Oral Irrigator earned perfect scores for ease of use, effectiveness, and overall value. Though we appreciate that it has five modes, we knocked off half a point for settings since the higher speeds were a little too strong, making it harder to control and splashing water everywhere. That said, the softer modes were not only plenty effective but also comfortable and manageable.
While the instruction manual wasn't very thorough, our tester found the product design intuitive and user-friendly. This cordless wet flosser has a rechargeable battery and a generously sized 13.5-ounce water reservoir. It comes with six heads, including two jet tips, a tongue cleaner, a periodontal tip (to flush out the gums), and an orthodontic tip (for braces and retainers).
Based on the ample features and high-end functionality, our tester was surprised by the wallet-friendly price point. All things considered, we wouldn't hesitate to recommend this water flosser to a friend and anyone else looking for an affordable, effective model.

Magnetic dock
10 intensity modes
Quad-stream tip for easy use
Large lidded reservoir
Reservoir dock is somewhat bulky
It's not cordless
If you're open to investing in a top-shelf model, the Power Flosser 5000 is a solid choice. The instructions are clear, and setup is simple — all you do is plug it in and fill it with water. Our tester tried it out after eating a plate of nachos and said her mouth was left completely clean. It's easy to toggle between the 10 intensity modes, and the quad-stream tip delivers four streams of water for a more thorough whole-mouth cleaning.
This water flosser has a large 18.6-ounce lidded reservoir, so you won't have to refill it mid-session. It isn't cordless, so you won't have to worry about recharging it, though it's not very travel-friendly.
The flosser itself is compact and lightweight. And while the reservoir dock will take up some counter space, we appreciate that the handle attaches magnetically to the base. The price is steep, but we think it's worth it based on the settings and effectiveness.

ADA Seal of Acceptance
Easy to use and set up
Long-lasting charge
Only has three pressure settings
Higher price point
We tried 12 Waterpik models in the Lab. Though a few of them fared well with our testers, the brand's Cordless Advanced Water Flosser (WP-560) was our favorite. Earning perfect scores for ease of use and effectiveness, we liked how the intuitive two-button design left our tester's teeth smooth and clear of debris. Although it only has three pressure settings, this is part of what makes it so user-friendly.
This cordless wet flosser is powered by a lithium-ion battery. Thanks to the rapid-charging system, it recharges in just four hours and lasts up to two months. The removable reservoir is also easy to fill. While it's only 7 ounces, you'll have enough water for a one-minute flossing session.
We also like that it comes with four heads, including two standard jet tips, an orthodontic tip, and a "plaque seeker" for precision cleaning. The price of this water flosser is higher than average, but considering the convenient design, included attachments, and effectiveness, we think it's a decent value.

Five intensity modes
Two-minute built-in timer
Seven interchangeable heads
There's a slight learning curve to this advanced flosser
Higher price point
For deeper cleans, we recommend MySmile. With five water-pressure modes and a two-minute timer, the brand's Cordless Oral Irrigator earned perfect scores for effectiveness and settings. It comes with eight heads, including two regular jets, a high-pressure tip, a lower-pressure tip, a "plaque seeker," an orthodontic tip, a "pik pocket" for gums, and a tongue cleaner.
Our tester found this wet flosser generally easy to use, though she had to play around with it a bit to figure out how to change the heads and use the different modes. Still, she said it did an excellent job cleaning her teeth and getting into hard-to-reach crevices.
We also like that the handle shows the water temperature and how much battery life is left. The Cordless Oral Irrigator is not only effective but also fun to use. We think it's worth the price and would recommend it to anyone looking for a high-tech wet flosser.

Allows you to simultaneously brush and floss
10 water-pressure levels
Two speeds
Sleek design
Very expensive
Large countertop footprint
Interested in an all-in-one gadget for at-home teeth cleaning? Look no further than the Waterpik Sonic-Fusion 2.0. Though it boasts three modes, two brush speeds, and 10 water-pressure levels, this electric toothbrush-flosser hybrid is intuitive and user-friendly. It's easy to change the settings, and you can even brush and floss at the same time.
Our tester said it immediately removed food stuck between her teeth and left her mouth feeling noticeably cleaner and fresher. We like that it has a large 16-ounce reservoir with a magnetic head holder. While you’ll need to make room for the base on your bathroom counter, our tester was a fan of the sleek appearance, compact handle, and time-saving design. It also comes with a travel case for the toothbrush component.
This is one of the more expensive water flossers we tried. But considering the convenience of a brush-floss combo and impressive results, we think it's worth the investment.

Most wet flossers have multiple modes, such as pulse and steady stream. Many also allow you to change the speed or intensity of the water pressure. "The pressurized water is excellent at washing away caught food and plaque from in between teeth and around the gumline," says Dr. Rhonda Kalasho Zoumalan, DDS, Hollywood's leading cosmetic dentist.
A higher-end model may have more settings, though this doesn't necessarily mean it'll do a better job cleaning your teeth. The most important thing is that it's user-friendly, comfortable, and easy to toggle between modes.
Water flossers often have other notable features beyond modes and pressure settings. This includes interchangeable heads, a 360-degree rotating nozzle, a built-in timer, rapid charging, a battery indicator light, a magnetic base, or a travel case. Our best overall pick, the Aquasonic Aqua Flosser, includes extra heads, a two-minute built-in timer for optimal cleaning accountability, 360-degree rotary tips, and a travel bag, too.
When browsing models, pay attention to the power source. Many modern wet flossers run on rechargeable lithium-ion batteries, which typically means they're cordless. They often charge fully in just a few hours and can last for weeks, if not months. Others have corded designs, in which case the water reservoir is usually separate from the handheld flosser.
You'll also want to consider the portability of your wet flosser. If you travel often, a cordless model with a rechargeable battery and carrying case might be your best bet. But if you only plan to use yours at home, prefer a larger reservoir, or don't want to worry about recharging it, a plug-in model may be a better choice.
Some water flossers carry a Seal of Acceptance from the American Dental Association (ADA), like the Waterpik Cordless Advanced Water Flosser. When you see the seal, you know a product meets the organization’s strict criteria for effectiveness and safety and that it lives up to its marketing claims.
A water flosser is an oral irrigator that flushes your mouth with pulsating water to get rid of gunk between the teeth, clean hard-to-reach areas, and prevent bad breath.
When used correctly, water flossers are great devices for removing stuck-on food and debris caught in your teeth. The high water pressure and rotating heads help get into those hard-to-reach places like the back of your mouth or close to your gum line.
Waterpik is a popular water flosser brand, so no, there is no difference. We tested 12 Waterpik models in the lab. While all were efficient water flossers, our favorite was the Waterpik Cordless Advanced Water Flosser.
We selected 26 wet flossers to try first-hand in the Lab. Our testers carefully evaluated each model's design and features, then followed the manufacturer's instructions before attempting to clean various sticky foods from their teeth. Each flosser was then scored for ease of use, effectiveness, and settings.
After considering the price and whether we'd recommend the products or repurchase them for ourselves, each water flosser also received a score for overall value. Those with the highest average ratings were ultimately chosen for this roundup.
We created the PEOPLE Tested seal of approval to help you find the very best products for your life. We use our unique methodology to test products in three labs across the country and with our network of home testers to determine their effectiveness, durability, ease of use, and so much more. Based on the results, we rate and recommend products so you can find the right one for your needs.
But we don't stop there: We also regularly re-review the categories in which we've awarded the PEOPLE Tested seal of approval — because the best product of today might not be the best of tomorrow. And by the way, companies can never buy our recommendation: Their products must earn it, fair and square.
In short, PEOPLE Tested provides recommendations you can trust — every day, every purchase.
