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.

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.

Pros

• 10 different floss and massage modes

• 90 seconds of continuous water

• Three-year limited warranty

Cons

• Can reportedly be very noisy

Best Features

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

Cons

• Inconvenient button placement

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

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

Turewell Water Flosser

This simple and attractive irrigator from Turewell boasts a 600-milliliter water tank, 10 different pressure settings, and compatibility with Waterpik jet nozzles. If you have braces or other circumstances that make it tricky to floss the old-fashioned way, this affordably priced cleaning system should do wonders for your teeth and gum health. 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.

Pros

• Works with Waterpik jet nozzles

• 10 different pressure levels

• 600-milliliter reservoir

Cons

• Some cases of leaks or motor failure

Benefits of Using a Water Flosser

Water flossers aren’t a replacement for flossing with regular dental floss, but using them regularly has a host of dental benefits. Water flossers can remove more plaque and residue than brushing alone can, so when you pair using the best water flosser with the best floss, you have a winning combination for a healthy mouth. Water flossers are also unmatched at reaching hard-to-get spots in your mouth (think your back molars) that often get skipped when flossing with regular floss and even brushing — and the pressurized water stream can even reach below the gumline and into otherwise inaccessible periodontal pockets. The result is a healthier mouth, with stronger gums and better breath.

Water Flosser vs. Traditional Flossing

The best water flossers and the best dental floss both have the same aim — cleaner, plaque-free teeth. But they’re best thought of as complements to each other, getting the best results when used in tandem.

• Traditional floss: The best floss is incredibly effective at getting in between tightly packed teeth to physically scrape plaque, food, and anything else off the teeth before it can build up. It’s inexpensive, takes up almost no room in a drawer, and you can get it anywhere. However, it can be difficult to get your fingers and the floss into notoriously tight spots (think the back molars) which makes incorrect flossing or skipping the spot more likely. Flossing too hard can also cause bleeding, and users with limited dexterity from arthritis or any other reason can find the small motor movements required to manuever the floss where it needs to go challenging.

• Water flossers: Water flossers excel at removing plaque and debris from hard-to-reach areas, including below the gum line, that regular floss can’t touch. The adjustable pressure of water flossers means even sensitive users can get a thorough clean without pain. On the other hand, water flossers are costly and incur further cost to use since they need to be powered (whether that’s being plugged into an outlet or with batteries) and refilled with water. They need regular cleaning, and they take up space on your counter.

So which is better? We recommend using a water flosser after flossing to take advantage of both their strengths. However, users with mobility limitations in their hands, sensitive gums, or dental appliances may especially benefit from water flosser use.

Key Features to Look for in a Water Flosser Device

The best water flosser for you is one you’ll use. To narrow it down, here’s what we recommend looking at. * Water Pressure Settings and Modes: Pressure that’s too forceful will hurt your gums; pressure that’s too weak won’t clean adequately. The best water flossers let you adjust the amount of pressure (measured in PSIs) in the stream to find the right intensity for your needs. Some models also have preset modes like gentle mode, normal mode, or massage/pulse settings that let you select a given pressure and stream type for ease of use.

• Reservoir Capacity: Larger tanks don’t need to be refilled as often, but take up more space on your bathroom counter. Smaller tanks are a better fit for bathrooms short on space or for those who want to travel with their flossers.

• Specialized Tips: If you will be using your water flosser for specific dental needs (or sharing your flosser with family members with differing needs), interchangeable tips can ensure you get the most out of the device. Apart from a standard angled jet tip, some models come with swappable tips that can include orthodontic tips designed to more thoroughly clean braces and retainers; plaque seeker tips with thin bristles meant for cleaning around dental implants, bridges, and crowns; and periodontal pocket tips made with rubber designed to aim a gentle stream below the gumline.

• Ease of Use: The right water flosser is designed to make your life easier. Features like easy-to-fill reservoirs, cordless design, and quiet motors, as well as easy tip storage can make a big difference in how often you want to use your water flosser

More Efficient Cleaning for Braces, Dental Implants, and Dental Appliances

If you’re dealing with braces, expanders, dental implants, bridges, crowns, or any other kind of dental appliance, you know that keeping the surrounding teeth and gums clean and plaque-free can be a major challenge – and a water flosser can be a major help. The gentle streams of pressurized water emitted by a water flosser are unparalleled at reaching awkward or hard-to-access areas that brushing and regular flossing can inadvertently skip. Using specialized tips can make it even easier.
