Some of us find joy in gum maintenance, but for those who don’t, a water flosser can make taking care of your mouth less of a chore. Studies show that flossing prevents gum disease and improves overall oral health. We know it’s important, but it’s not everyone’s favorite activity. One way to make flossing more efficient, convenient, effective, and pleasant? The water flosser.
Instead of using a string to get in between your teeth, water flossers are oral irrigators that use high-pressure water streams to remove plaque, bacteria, and food from your gums. Think of it as a pressure washer for your mouth. In order to help you pick the best option for you, we selected five of the best water flossers on the market so you can improve your oral hygiene and make your dentist proud.

We considered a wide swath of information, including outside reviews to determine the models for inclusion. We analyzed products for their tip types, so that we could offer you suggestions for different types of use. Finally, we looked at the value for the price. We don’t want to recommend a bunch of products that are absurdly pricey if they’re not going to make you smile.

Things to consider before buying the best water flossers
If you’re new to water flossing, it can be overwhelming to decide on which product is best for you. Here’s what to look for:
Type
Before you begin shopping for a water flosser, you may want to know the types of flossers on the market so you can choose the best product for your intended use.
Countertop: These are usually the bulkiest options because they tend to come with the most features. Since they’ll primarily be staying put on your countertop, they are not best for travel or easy portability, but are great for a range of pressures and options.
Cordless: These are generally best for travel and on the go use, or if you don’t have a lot of counter space to spare. They might not have as much power and pressure as the traditional countertop, but they are great for convenience.
Flossing toothbrush: Just as the name suggests, this is a water flosser-toothbrush combo. It has water flossing capabilities on the brush head so you can get an all-in-one experience.
Water pressure
This affects how powerful your water stream will be. Depending on your gum sensitivity, too much pressure might be uncomfortable and could even cause bleeding. You want to make sure you purchase a water flosser with enough pressure to be effective, without causing pain. This can be tricky since there’s no hard metric companies offer to judge that’s easy to compare, but the different types of tips can give you a hint about what to expect.
Reservoir capacity
While some water flossers feature reservoirs with enough space to last 60 seconds of flossing time, others may be smaller or bigger depending on the model. How long the water lasts also varies depending on attachments and pressure.
Portability
If you intend to travel with your water flosser, you’ll want a product that’s compact and easy enough to move around. Look for cordless models, and/or products that come with cases.
Tip type
There are several brush heads depending on your needs: Regular, Orthodontic (for braces), Plaque Fighting (great for more severe cases of plaque) and Toothbrush tips are the most common.
FAQs
It depends. While research from the National Library of Medicine does show that water flossing may be more effective in fighting gum disease, and is better for reaching periodontal pockets and plaque, the argument is really about which method you’ll actually do.
If you don’t enjoy water flossing, you won’t reach for the water flosser and consequently, won’t floss at all. So, the best method is the method that you’ll be most consistent with.
Some people find water flossing to be a bit messy, especially at the beginning when they’re first getting used to the product. It’s also a more expensive purchase than string floss, and can be bulky and take up a lot of space in your bathroom.
Yes. According to the American Dental Association, the Waterpik water flosser, specifically, has shown to be safe and efficient in removing plaque. It’s also been shown to help prevent and reduce gingivitis.
You can share a water flosser if you use your own brush tip. Think of it like sharing a toothbrush (yuck!). So, we recommend sharing the base or wand but switching out the heads for each member of your household.
It ranges! Budget options can range between $40-$50, while more premium models can be well over $100.
