As a general rule, dentists are big fans of flossing. But they’re well aware that not everyone shares their zeal.

“In my 30-plus years of experience, I have found flossing to be very difficult for most patients,” says Dr. Mitchell A. Kaufman, a dentist and periodontist with NowDental in Bellmore, New York. “Especially for the back teeth.”

Dr. Guneet Alag, a dentist at Fab Dental in Hayward, California, notes that people with limited dexterity aren’t always able to use floss effectively. And “if string floss is used incorrectly or too aggressively,” she says, “it could cause trauma to the teeth and gum tissue.” Flossing is also tough for people wearing braces.

Enter the water flosser — a device that uses pressurized water to clean the gaps between teeth. Though few dentists consider a water flosser a replacement for string flossing, there are significant benefits to adding one to your personal care routine.

“Water flossers are easier for some people,” says Dr. Tyler Hales, a dentist with Facer Hales Parker Dentistry in Ladera Ranch, California. “The goal is to do it, and if the patient likes it then they will do it more.”

Whatever your reason for buying a water flosser, you have over a dozen brands to choose from. Where to begin? We asked several dental experts to recommend the best options in various categories.

Every dentist interviewed began by recommending Waterpik. “It’s the OG, which is why it’s the number one brand,” says Dr. Scott Cardall, an orthodontist and owner of Orem Orthodontics in Orem, Utah. But he notes that other brands could also be beneficial depending on the special features they offer.

As the dental experts evaluated water flossers in various categories, they considered several factors. Here are the criteria to keep in mind when making your own decision.


What To Look For

Multiple Pressure Levels:

“I always tell my patients to buy one that has different pressure level options,” says Chicago-based registered dental hygienist Whitney DiFoggio. “Always start on a low setting. If it feels good, then continue using that setting. If you can barely feel it, then turn it up. You want to feel the gingival stimulation, however, you do not want it to sting or hurt!”

Reservoir Capacity:

Countertop water flossers have a separate water tank, while portable models have a reservoir that’s attached to the flosser itself.

Dr. Cardall prefers the countertop models with a separate tank because “the reservoir can store much more water/irrigant before running out.” For example, a standard Waterpik tank holds 22 ounces, which allows you to floss for 1 1/2 to 2 minutes before you run out of water.

With a portable water flosser, your reservoir may hold as little as 5 ounces, so you’ll have to refill it two or more times during a single, two-minute session of flossing. Of course, if you have a tiny bathroom — or portability better suits your lifestyle — you may be happy to sacrifice the large water tank.

ADA Seal:

“The ADA seal of approval can offer you assurance that your dental tool has been verified for safety and efficacy,” says Dr. Alag. “Waterpik and Philips Sonicare are the only brands with ADA approval currently.”

Cost:

Water flossers can cost anywhere from under $20 or over $150, depending on the model and brand you buy.

Special Features:

These might include extra tips (which typically need to be replaced about once every six months) or a 2-in-1 flosser and electric toothbrush combination.

“Waterpik is a  reliable and well-established brand,” says Dr. Jennifer Silver, a dentist at  Macleod Trail Dental in Alberta, Canada. As an overall good choice, she recommends the Aquarius “for general oral hygiene because it’s effective for those with normal gum health.” It has 10 pressure options and holds enough water for 90 seconds of flossing time.

Nearly all the dentists interviewed mentioned this innovative toothbrush-flosser combo, because it allows you to brush and floss simultaneously. “I believe if you make something convenient and easy for patients they are more likely to use it,” Dr. Kaufman says. “We have noticed a marked difference in our patients’ overall oral hygiene when they use this product.”

And the brush itself is top-quality: “The toothbrush has a really good bristle tip speed, that provides extra plaque removal and promotes gum health,” says Dr. Shahrooz Yazdani, CEO and Director of Costello Family Dentistry in Ontario, Canada.

While this water flosser isn’t by Waterpik, Dr. Silver likes that it’s “professional-grade and rechargeable.” Its ergonomic design makes it comfortable to hold, and it comes with four extra tips. The small reservoir holds enough water for 30 seconds of flossing, so it will have to be refilled at least once.

This flosser has 10 pressure levels and a good-sized water tank.

    • Pros: Large reservoir capacity, 10 pressure settings

    “A water flosser can also enhance the effectiveness of tooth-whitening treatments,” says Dr. Alag. The Waterpik Whitening Water Flosser claims to floss your teeth while also restoring them to their natural whiteness in four weeks. A whitening tablet inserted into the flosser’s flip-top handle infuses the water with a stain removal agent that also works on plaque and boosts gum health — without harsh bleaching chemicals.
