Dentists say that flossing is one of the most important things you can do to keep your mouth healthy and clean. But what if you don’t like string floss, or have sensitive gums, braces and/or dental work? It might be time to try a water flosser instead. Similar to regular flossing, water flossing removes food, debris, and any lingering bacteria that could eventually turn into plaque. Like regular floss, water flossing can help prevent gum disease. And since it tends to be more gentle than using string floss, it can reduce bleeding.

Whether you want a cordless, portable, or toothbrush and water flossing combo set, we’ve rounded up the best water flossers of the year.  

How We Picked the Best Water Flossers

Methodology

To select the top five water flossers, we considered products from ten different companies. The most important factor was versatility. Can this product work for multiple users? How many settings and modes does it have? Water flossers with different modes (typically soft, normal, strong, or pulse are offered) can accommodate different mouths. The same is true for water pressure and other settings. 

We also looked at specific criteria such as whether or not the flosser was cordless, how much water the reservoir holds, portability, and number and usage of additional nozzles. For those with limited counter space in their bathrooms, was there a detachable tip for each person to use in the family? We wanted to offer products that would accommodate specific user needs whether that’s related to braces, budgets, or frequent travel.

Things to Consider Before Buying a Water Flosser 

Before you ditch the floss and invest in a water flosser, here’s what you should keep in mind: 

Cordless vs. Plug-In

Water flossers fall into two main categories: cordless or plug-in. Cordless flossers typically contain a battery and must be charged with either a plug or a charging base. One full charge can last anywhere from a week to a month. Water flossers that you need to keep plugged in, as with other products that require a plug, offer more stability but can take up more counter space. The choice is ultimately up to personal preference. 

Budget

You shouldn’t have to sacrifice a healthy mouth if you’re on a budget. Luckily, when it comes to water flossers, you don’t have to. You can get a great flosser for less than $40. When selecting which one to buy, don’t forget to read all of the details and specs to ensure it has everything you need. 

Multiple Modes 

If you’re new to the world of water flossing or have sensitive gums, most companies recommend first using less water pressure and a softer mode until you get your bearings. Once you have some experience using the flosser, you can change the mode and alter the settings. Having a water flosser that has multiple usage modes and a range of water pressure settings can be extremely helpful. 

FAQs

Q: Do dentists approve the use of water flossers?

While water flossers can help remove food particles from your teeth, reduce bacteria from the gumline, and possibly aid in reducing bleeding and gum disease, most dentists don’t consider them a substitute for brushing and using dental floss. Water flossers don’t generally remove plaque and film from your teeth as well as string floss does. 

Q: Are water flossers bad for your gums? 

Water flossers are not bad for your gums. They may actually cause less damage than dental floss because they don’t put as much pressure on your gums. 

Q: How often should you use a water flosser? 

Water flossers should be used at least once a day, preferably before you brush your teeth, because removing food particles and debris enhances the effectiveness of tooth brushing. Flossing before brushing is the best way to increase the fluoride concentration that is delivered by using toothpaste. 

Final Thoughts

The best water flosser will have features that accommodate your specific and personal oral healthcare or household needs. Whether you have countertop space limitations, don’t have an electrical plug in your bathroom, or you have braces, bridges or sensitive gums, the water flosser you buy will provide a deep cleaning as well as fit comfortably into your space and lifestyle.
