Whether you’re looking to improve your long-term gum health, help out your toothbrush, floss around things like bracers and permanent retainers, or just want to keep your teeth sparkling clean on long business trips, water flossing can change your oral health for the better. But it’s something you’ll want to ask your dentist about; in many cases, it works best as a supplement to string flossing, rather than a full replacement.
Water flossers come in a variety of sizes and price ranges, but their main differences are pretty straightforward: reservoir size, power source, and accessories. Interchangeable tips help you with various oral-hygiene-related tasks as well as letting you share the irrigator with family members.
Your tolerance for water pressure may be a factor in your decision, as some of the higher-powered products have fewer pressure settings and modes than others—you don’t want something that’s going to cause you pain. A larger reservoir will generally be better if you’re keeping the flosser in one bathroom all the time; it’ll save you having to refill the device midway through flossing.
Here are some of the best water flossers, oral irrigators, and water picks to shop online now.
Editor's Note:
The recommendations in this guide are based on thorough product and market research by our team of expert product reviewers. The picks are based on examining user reviews, product specifications, and, in some limited cases, our experience with the specific products named.
Best Overall
Waterpik Aquarius Professional Water Flosser
This best-selling Waterpik flosser offers 10 different settings, has been approved by the American Dental Association, and is backed by a three-year warranty.
If you’ve got braces or other dental work that makes it tricky to floss the traditional way, the Aquarius delivers water pressures up to 100 psi from a 22-ounce reservoir, all powered by a simple plug-in cord. The reservoir can go in your dishwasher, and it’s got a variety of useful tips for tasks like brushing and tackling hard-to-reach areas.
Reviewers have found the customer support to be excellent, though some weren’t thrilled about the flosser’s noise level. However, with its powerful cleaning abilities, it's the best oral flosser for most people.

MySmile Cordless Oral Irrigator
This cordless water flosser from MySmile can deliver a 150 psi stream of water, offering a deep, powerful clean. It’s got several steps to initiate spraying, so you shouldn’t have many watery mishaps, and its display will keep you informed about battery life and so on.
The nozzle can rotate 360 degrees, the reservoir can hold up to 350 milliliters of water, and there are five different cleaning modes, including “pulse” and child settings. When fully charged, the battery ought to last about 15 days or so with regular use; the charging cord is a convenient USB input.
In addition to the oral irrigator and charging card, you also get eight replacement tips, a storage bag, and a user manual out of the box. One reviewer pointed out that it’s easy to detach the nozzle when aiming for the power button, which can lead to water spraying everywhere—or in your face. But the MySmile offers a great alternative to regular flossing.
Pros
-
Five different cleaning modes
-
Water pressure up to 150 psi
-
350-milliliter reservoir

Best Portable
Waterpik Cordless Express Water Flosser
This small, portable Waterpik is one of the best oral flossers for traveling or as a backup away from your main bathroom. It’s got a flow rate of about 237 milliliters per minute, but its water tank only holds about five ounces of water, so you’ll find yourself having to refill after about 30 seconds of flossing.
It only has two pressure settings, with a maximum of 75 psi, but you may really love the convenience of battery power; it runs on three AA batteries, as opposed to having to recharge or find an outlet. A good set of batteries should last you through a couple months of daily flossing.
Pros
-
Portable and travel-friendly
-
Runs on three AA batteries
Cons
-
30-second water reservoir
$37.97 from Amazon
Aquasonic Aqua Flosser
The Aquasonic is my first water flosser, so my main basis for comparison is traditional flossing—or a trip to the dentist. And, so far, I’ve been pleasantly surprised across the board. It came precharged right out of the box, and the battery seems to last a good while. It’s also small and lightweight for something with a built-in battery and a water reservoir.
There’s a plastic cap on a hinge that you flip open to fill it up, and then from there it’s just a single button press to start flossing. It has an on-and-off button as well as a separate selector button for cycling through the different cleaning modes: normal, soft, and pulse. These light up to let you know what mode you’re on as well as to indicate when the flosser’s plugged in and charging. I didn’t expect it to be so user-friendly.
And it feels great. The full-strength “normal” mode hasn’t hurt my gums; it leaves my mouth feeling cleaner than if I were to settle for something like floss picks. And it won’t add a ton of time to your existing routine.
Pros
-
Good battery life
-
Portable
Cons
-
Small water reservoir
-
So-so water pressure

Its attachments include three ordinary, high-pressure tips as well as five specialty jets for cleaning your tongue, removing plaque, and brushing your teeth.
It’s got 10 water pressure settings with a maximum of 125 psi. And you can simply plug it into an electric outlet for power, which some shoppers might prefer over having to recharge a battery. Some users report leaky products, or motor failure, but most are happy with this basic yet powerful Waterpik competitor.
