6 Best Water Flossers, According to Our Tests

This is a water flosser that does it all: Receiving top marks across the board for its mess-free deep cleaning, ease of use and quietness, the Philips Sonicare water flosser rated 96% in overall satisfaction among our consumer testers, with one even describing it as their "all-time favorite" product throughout 20 years of using water flossers.

Its four water stream settings (clean, deep clean, sensitive and massage) and auto-timer setting allow you to really get into your gums for a through clean. "With my old flosser, I think I moved too fast between my teeth to do an effective job," said one tester. "I feel like I have now completely re-learned the correct way to use water flossers."

Featuring the longest hose among the models we tested, the almost four-foot long retractable cord and magnetic handle make it easier to navigate your mouth (not to mention store away when not in use). Reservoir fills are easy thanks to a flip lid. Plus, if you value counter space, testers said they preferred this model's sleek design to other clunkier versions they've tried in the past.

Lightweight and simple to use, the Waterpik ION countertop model couples most of the bells and whistles you'd find in a more expensive water flosser, but at a lower price point. With an impressive 3-star Quiet Mark score, we found it to be one of the quietest water flossers we tested. It also got high marks for its ergonomic design and effective between-teeth cleaning, according to our testers. The retractable hose keeps countertop clutter minimal, but if you'd like to go cord-free, the flosser includes a rechargeable battery too. "I love that it's wireless, and [it] can sit anywhere I want on my sink!" said one tester.

Switch between its six tips, including a standard jet tip. If you're looking for the best Waterpik for implants, there's also an orthodontic tip that a tester said cleaned underneath "painlessly" and "with ease," adding that "I have one [area] that floss cannot reach, and this made it a breeze to reach ... my dentist is going to be thrilled."

At under $40, Waterpik's cordless model is significantly cheaper than many other water flossers on the market. For that reason, it's a great choice for anyone who's curious but hesitant about trying an oral irrigator.

Despite its lower price, this space-saving model packs in water pressure that matches that of a full-sized Waterpik. Small, lightweight and cordless, it's a great option for travel too, earning a perfect score for not taking up too much countertop space in our tests. Though it requires more frequent reservoir refills than other models we tested, it scored the best among handheld devices for having an easy-fill tank.

Even though it only has two settings, the switch makes it easy to change the water pressure. It uses three AA batteries, so you don't have to worry about misplacing a charger. The reservoir holds five ounces of water (equivalent to 30 seconds of use), and it has a removable tank that's super easy to clean – just throw it in the dishwasher on the top rack.

Upgrade your floss game with a water flosser that even novice users can enjoy. Smile Direct Club's handheld teeth cleaner rated highest in our ease of use tests for its easy-to-follow manual, and at just $40, our testers enjoyed its cordless capabilities, especially since you can use it in the shower. It rated 98% in overall satisfaction for cleaning in between teeth better than traditional string floss. The well-sized cordless water tank also requires fewer refills than comparably sized models.Holding a stronger charge and stream than one tester's current flosser, they said it "felt good on my gums" and "made me feel that I was doing something better for my oral health than I was previously doing."

With an average 4.6-star rating across nearly 121K+ (!) reviews, Waterpik's Aquarius model has earned its spot as one of the best-selling water flossers on Amazon. "After every use, my mouth feels like it was cleaned by a dental hygienist" raved one reviewer. Its large reservoir holds up to 22 ounces of water (or mouthwash), which should equate to about 90 full seconds of flossing time — roughly three times more than most wet flossers. It also features a separate mode that pulses water to massage your gums.

It comes with seven tips that serve different purposes: three classic, one for plaque, one for braces, one for periodontal pockets and one with a toothbrush head. Bonus: It's available in other colors, like gray — since it's going to stay on your countertop, the more color options, the better, we say.

You can fit this battery-powered water flosser onto even the smallest of countertops, but don't be deceived: Testers noted you don't have to sacrifice strength for size with this pick. It offers "lots of power for a compact size," one tester said. The model collapses down to five inches for easy travel and storage and pops back up to double the size. Beyond its convenient compact design, it also makes a great pick for beginners, thanks to its easy-to-follow manual and it comes with normal, soft and pulse settings. "The water pressure was perfect for getting between my teeth without irritating my gums or nerves," another tester noted.
