Best Wet Flossers

Verywell / Sabrina Jiang

Interdental cleaning—cleaning between the teeth—is a vital part of any dental hygiene routine. Unfortunately, you can't always rely on toothbrushes to get the job done thoroughly. But interdental devices—like wet flossers—have been specifically designed to target those hard-to-clean areas.

Some research suggests that adding wet flossing to your routine can improve your dental hygiene. One clinical trial showed that people who wet floss once a day and brush their teeth twice a day had improved gingival health compared to people who simply brush twice a day and don’t wet floss at all. Other research has indicated that routine wet flossing (in addition to regular brushing) can cut down on plaque and reduce gum bleeding.

“While waterpiks do not replace the function of conventional floss, they can certainly serve as a helpful adjunct for at-home dental hygiene maintenance,” says New York City-based dentist Heather Kunen, DDS, MS, co-founder of Beam Street.

If you're looking to upgrade your dental hygiene routine, you may want to consider using a wet flosser. We researched dozens of water flossers and evaluated them for reviews, reservoir capacities, number of pressure settings, ease of use, comfort when using, pricing, and return policies. Each of the flossers chosen in this article were determined to be the best of these factors.

Here are the best wet flossers on the market today.

Best Overall: Waterpik Aquarius Water Flosser

Waterpik
Pros
  • Ten different pressure settings

  • Massage mode improves circulation in gums

  • Includes seven tips for a custom cleaning

Cons
  • Bulkier than other models

  • Can be loud

Waterpik is widely considered to be a best-in-class brand, with five of its product lines receiving the American Dental Association (ADA) Seal of Acceptance. Among them is the Waterpik Aquarius Water Flosser, a wet flosser that improves gum health and brightens teeth with daily use. 

The Waterpik Aquarius Water Flosser has 10 different pressure settings, so you can select the intensity that best meets your needs. The wet flosser also comes with an additional massage mode designed to stimulate the gums. Like many wet flossers, the Waterpik Aquarius Water Flosser comes with seven different tips, each of which can be easily attached to (or detached from) the water flosser. Many of these tips cater to specific dental needs like orthodontics, periodontal pockets, and implants, making it easy for you to customize your clean.

The Waterpik Aquarius Water Flosser holds up to 22 ounces of water at a time. This will allow you to get an uninterrupted clean for a full 90 seconds (and since Waterpik recommends using the product for a minute each day, this is more than enough). The Waterpik Aquarius Water Flosser also automatically pauses at 30 seconds and 60 seconds, so you can keep track of how long you’ve been flossing without setting a separate timer.

Charge Type: Electric charge | Reservoir Capacity: 22 oz | Number of Pressure Settings: 10


What Our Editors Say

"I've been using the Waterpik Aquarius for about four years and want to give one to all of my friends because my teeth and gums feel so clean and healthy. I have permanent retainers on my top and bottom teeth, and this easily removes bits and pieces so I don't have to thread floss through every single space. Using this water flosser has also made dental cleanings easier because I have less plaque and healthier gums!" — Nicole Kwan, Editorial Director of Verywell Health

Best Cordless: Waterpik Cordless Water Flosser

Pros
  • Good for small spaces and traveling

  • Three water pressure settings

Cons
  • Limited reservoir capacity

The Waterpik Cordless Waterflosser offers the high-quality clean you’d expect from a Waterpik product with the convenience of a smaller, cordless wet flosser. The flosser has a streamlined design that makes it easy to hold, wield, and carry on-the-go. Because the flosser is cordless, it’s incredibly travel-friendly, and you won’t have to worry about your flosser taking up a ton of precious counter space with its compact design. Not to mention, a cordless design makes maneuvering much easier.

“You should be able to use it efficiently and effectively across the whole smile line, not just at the front of us, wires and connections can make that more difficult,” says New York City-based dentist Lisa Creaven, DDS.

Though the Waterpik Cordless Waterflosser is relatively small, it’s not too small to be useful. The flosser’s reservoir can hold about 7.6 ounces of water—that’s enough for 45 seconds of flossing. If you want to floss longer, you can easily refill the device and continue, and you can simply use the 45-second cut-off point to keep track of how long you’ve been flossing. It has three water pressure settings, so you can opt for a gentler or more intense clean based on your needs and preferences.

Best for Braces: Waterpik Water Flosser for Kids

Pros
  • Colorful design and stickers for kids

  • Orthodontic tip is good for braces

  • Easy-to-use design

Cons
  • No cover on water reservoir

The Waterpik Water Flosser was designed with kids in mind and is ideal for cleaning braces. The wet flosser is small, colorful, and relatively simple compared to some of the other adult-oriented options on the market. It only comes with three water pressure settings and two wet flossing tips: one standard wet flossing tip, and one orthodontic tip. The flosser’s simplicity means it should be straightforward and easy to use for kids.

But the Waterpik Water Flosser isn’t just painless and uncomplicated—it promises to be a little bit fun, too. The wet flosser’s lime green palette will make it a lively addition to any bathroom counter. And it comes complete with an array of “removable cling labels” (think: easy-to-remove stickers) kids can use to decorate and personalize their wet flossers.

Best for Bridges: BESTOPE Cordless Water Flosser

Pros
  • Five different cleaning modes

  • Eight different wet flossing tips

  • Full charge lasts 30 days

Cons
  • Reservoir must be refilled frequently

Dental bridges are used to fill in the gap left behind by one or more missing teeth. There are several different kinds of dental bridges, and depending on where bridges are in the mouth, they can be hard to clean. Thankfully, some wet flossers, like the Bestope Water Flosser, make it easy to clean these hard-to-reach areas.

The Bestope Water Flosser comes with eight different wet flossing tips that can rotate 360 degrees, giving you access to areas you may have a harder time reaching with a standard toothbrush. The Bestope Water Flosser offers five different pressure modes—soft, low, medium, high, and super high—so you can customize the intensity of your clean based on your needs and preferences.

Because the Bestope Water Flosser is cordless and rechargeable, it’s easy to take with you on-the-go. A full charge should last you 30 days, so you won’t have to worry about constantly recharging your wet flosser. The Bestope Water Flosser’s reservoir holds up to 300 mL of water at a time, and is easy to remove, refill, and clean. So even if you have to refill the reservoir mid-floss, you can rest assured knowing that doing so is relatively easy. 

What the Experts Say

“The biggest benefit and patient comfort from water flossing is patients with veneers, bridges, and implants. That's where I see the biggest benefit of using water flosser. They're nervous about using floss and they don't go with [traditional floss] because they're nervous, and then that obviously leads to its own issues long term.”—Lisa Creaven, DDS

Best for the Shower: Oral Breeze ShowerBreeze Dental Irrigator

Pros
  • Great for reducing bathroom counter clutter

  • Comes with two tips for oral cleaning

  • No reservoir to refill

Cons
  • Must use shower head to adjust pressure

The Oral Breeze ShowerBreeze Dental Irrigator attaches directly to your shower head, making it easy for you to multitask while getting ready in the morning. Simply install the wet flosser shower head attachment, turn on the shower, and twist the valve on the wet flosser until water begins to come out of it. You can use the knobs in your shower to adjust the temperature of the water. While many wet flossers offer discrete intensity settings, the Oral Breeze ShowerBreeze Dental Irrigator operates on a gradient; the wet flosser’s valve gives you complete control over the water pressure, so you can adjust it until it’s reached the exact intensity you’re looking for.

Because the Oral Breeze ShowerBreeze Dental Irrigator connects to the shower, you don’t have to worry about it cutting out and needing a refill mid-stream. It’s also free of the bulky reservoirs and attachments that tend to accompany wet flossers, so it saves time and space.

Charge Type: None, uses shower pressure | Reservoir Capacity: No reservoir | Number of Pressure Settings: 1

Best Two-in-One: Waterpik Sonic-Fusion Professional Flossing Toothbrush

Waterpik Sonic-Fusion Professional Flossing Toothbrush
Pros
  • Multifunctional toothbrush and water flosser

  • Has 2-minute timer and 30-second pacer

  • Ten different presser settings

Cons
  • More expensive

The Waterpik Sonic-Fusion Professional Flossing Toothbrush is an electric toothbrush and a water flosser in one. This combination design comes with two major benefits: first, it saves on counter space by combining your toothbrush and water flosser into one device. Second, it makes your dental hygiene routine more efficient with its three settings—brush, floss, and brush and floss.

Like many wet flossers, the Waterpik Sonic-Fusion Professional Flossing Toothbrush offers 10 different pressure settings, making it easy for you to get a clean that’s as intense (or as gentle) as you want it to be. It works on a two-minute timer with a 30-second pacer, so you can easily keep track of how long you’ve been brushing, flossing, or brush-flossing.

Best for Sensitive Gums: H2ofloss Dental Water Flosser

Pros
  • Gentle enough for use with sensitive gums

  • Twelve multifunctional wet flossing tips

  • Budget-friendly

Cons
  • Can be loud during use

  • Bulky design

The H2ofloss Dental Water Flosser may look a little bulky, but because it was designed with comfort in mind, its large size is a worthy trade-off—especially if you have sensitive gums.

“For those patients with sensitive teeth and gums, it is important to use a water flosser that has a lower-pressure setting as to not further traumatize their gums,” says Dr. Kunen.

This wet flosser delivers 1,200 water pulses per minute, thanks to an audience poll that determined 1,200 as the most comfortable pulse level in a water flosser. It comes with six pressure settings, so you can adjust the intensity of the water pressure to meet your needs. The wet flosser also comes with a built-in “pause” button on its handle, so you can easily stop the water flow if it starts to feel overwhelming or uncomfortable.

The H2ofloss Dental Water Flosser comes with 12 multifunctional wet flossing tips: four standard jet tips, two tongue-cleaning tips, two orthodontic tips, two periodontal tips, and two nasal tips. Opt for the tip that best meets your needs, or mix and match the tips to craft a wet flossing routine that works for you.

One positive of the H2ofloss Dental Water Flosser’s bulky form is that its reservoir can hold up to 800 mL of water at a time. That will allow you to wet floss for 150 uninterrupted seconds—no refills required.

Final Verdict

If you’re looking for a wet flosser that’s effective, space-efficient, and relatively budget-friendly, the Cremax Portable Dental Oral Irrigator (view at Amazon) is a great place to start. If you’re looking for something a bit higher-tech, you may be better served by the Waterpik Aquarius Water Flosser (view at Amazon), which has 10 intensity settings and comes with seven wet flossing tips.

What to Look for in a Wet Flosser

Reservoir Capacity

If you don't plan on traveling with your wet flosser, a flosser with a larger water reservoir will allow you to floss thoroughly before needing to refill. On the other hand, the larger the reservoir, the more clunky the flosser. If you plan on taking your device on the go, keep an eye out for a model with a smaller, more portable reservoir.

Battery Life

As is the case with reservoir size, you'll want to look for a rechargeable, battery-operated wet flosser if you plan to take it with you as you travel. That being said, a lot of the options on the market feature powerful chargers that keep the flosser powered for days at a time. If you're planning to travel, look for a model that has a longer battery life that won't slow you down when you're on the go.

Ease of Use

A rotating tip also makes a water flosser more user friendly. Angling any tip around the mouth to hit all the nooks and crannies can take practice, but a flexible or swiveling head helps. It also makes it more effective than manual flossing, especially for anyone with larger fingers or dexterity issues.

“Water flossers do not involve using your fingers or maneuvering your wrist, and have a wide handle that is easy to grip for those who have dexterity issues such as arthritis,” says Todd Bertman, DMD, the owner of Advanced Dental Arts in New York City. 

Dr. Bertman advises people shopping for a water flosser to look for one with an angled tip, which will allow you to get between the teeth as closely as possible. This, combined with the power of a water pic, can help spray away big pieces of debris and food particles that would otherwise be left behind.

Intensity

Every mouth is unique and the pressure needed to properly clean it is too. There’s also a wide range of gum sensitivity and size of the spaces between your teeth. According to Dr. Bertman, the pressure of a water flosser should be high enough to be effective, but not so high that it causes gum damage such as pain, discomfort, or bleeding. He does note, however, that water flossers are generally safe, and any damage caused by high pressure is likely to heal itself rather than be permanent.

To ensure you can personalize the pressure to fit your precise needs, you need a wet flosser with a number of pressure settings. From there, you can test each and determine which intensity level is best for you and your dental needs.

“If you are a first time water flosser, it is best to start at a low pressure setting and gradually work your way up,” advises Dr. Bertman. “Once you are more accustomed to the way it works, it will be easy to find a setting that works best for you.” 

Accessories

Most water flossers will come fully equipped, but some have optional tips and specially designed attachments to use with dental work, braces, and sensitive teeth/gums. “Those patients with braces or other fixed appliances who have trouble keeping them clean may benefit from daily use of waterpiks,” says Dr. Kunen. Dentists also recommend switching up the tip or head depending on your specific concerns. 

Frequently Asked Questions

  • Are water flossers better than conventional flossing?

    Traditional floss may be some dentists’ preferred choice, but consider water flossers an adjunct to brushing and traditional manual flossing. “It feels quite gentle but it is actually quite a strong force through the little triangle between the teeth,” says Dr. Creaven. “It’s actually pushing the food and debris so it will pop off of the teeth and away from that area.” Both conventional flossing and water flossing are good for getting a thorough clean, but conventional flossing should always stay in your dental hygiene routine.

  • Are there any risks to using a wet flosser?

    When it comes to safety, there are a few things to keep in mind. First, you don’t want to leave water in the reservoir. Dr. Creaven recommends emptying it after each use to ensure there’s never standing water to worry about. Another area of concern is excessive pressure. “Since water flossers utilize a pressurized water stream to remove plaque and debris, it is important that patients don’t traumatize their gums with the device,” says Dr. Kunen. “Patients must make sure to follow the directions of use in order to prevent any damage to their tissues.” The variety of pressure settings helps keep this in check.

  • How often should I use a wet flosser?

    The order of your oral care routine matters. Start with a water flosser and follow it up with a toothbrush. “We have a general rule of thumb that a water flosser should probably be used once a day, and use before brushing,” says Dr. Creaven. “As you brush your teeth, you have active ingredients in your toothpaste and you don’t want to wash away those ingredients after you brush.”

    Some research suggests that adding a water flosser to your routine can improve your dental hygiene significantly. One clinical trial showed that people who use a water flosser once a day and brush their teeth twice a day had improved gingival health compared to people who simply brush twice a day and don’t wet floss at all. Other research has indicated that routine water flossing (in addition to regular brushing) can cut down on plaque and reduce gum bleeding.

    “As long as those practices are maintained, I encourage those patients who like water flossers to incorporate them into their routines as often or as little as they like,” says Dr. Kunen.
