What is the Waterpik water flosser?
A water flosser is an oral health appliance meant to be used for dental care at home, instead of, or in addition to, traditional dental floss, depending on what your dentist recommends.
Water flossers consist of a motor with a pump, a water reservoir and a water flosser tip. The motor pumps pressurized water from the reservoir, through the tip and into your mouth. This stream of water removes plaque and food particles just like regular floss.
Waterpik is just one brand of water flossers that are available on the market. What sets the Waterpik apart is that it was the first of its class to earn the American Dental Association Seal of Acceptance.
A similar product is air flossers, which you can read about here.
What are the features to consider in the best Waterpik flosser?
Due to their efficacy and ease of use, water flossers have become quite popular, and as a result, there are many different kinds on the market. Here are some features you should keep in mind:
- Countertop: A countertop water flosser has a large reservoir base that holds enough water for repeated uses, and that means less frequent re-filling. Countertop models may also be more powerful than a cordless water flosser.
- Cordless: Cordless water flossers are not connected to a larger reservoir that sits on the countertop. Instead, they have a smaller reservoir that is built in to the handheld device. The best benefits of a Waterpik cordless water flosser are that it takes up less space, making them the best travel Waterpiks. The downsides are that it isn't as powerful as a countertop model and some have reservoirs that only offer a stream of water for as little as 30 seconds.
- Price: Waterpik flossers can range in price from $40 to $200, so you'll have to decide what extras you will pay for.
- Settings: Water flossers come with various settings, some even having up to 10. This can be very useful, especially if your family will be using it as well.
- Tips: All water flossers have standard water jet tips, and then some come with special tips for cleaning different things, such as orthodontics, your tongue, and implants.
- Electric toothbrush compatibility: If you prefer using an electric toothbrush but don't want to occupy any more precious countertop space, you should look for either a countertop unit that bundles the two items together or a cordless water flosser that is compatible with the charging base for your electric toothbrush.
Now, without further ado, let's have a look at some of best Waterpik water flossers on the market today.
Waterpik Aquarius water flosser
The Waterpik Aquarius is topping the list as one of the best-rated Waterpiks for most water flosser reviewers. This countertop water flosser has all the bells and whistles you could hope for. You may also see this listed as the Waterpik WP-660.
It includes 10 different water pressure settings that are easily chosen by rotating a knob on the side of the countertop component. One of the settings is a “pulse modulation” mode that first flosses your teeth and then massages your gums.
The tip rotates 360 degrees so you can easily get into normally hard-to-reach places and a timer beeps every thirty seconds to remind you to move on to a different part of your mouth.
This model also comes with seven tips: three classic jet tips, a toothbrush tip that lets you brush and floss at the same time, a plaque seeking tip, an orthodontic tip for braces and a tip for periodontal pockets.
The reservoir holds enough water for 90 seconds of use, which is more than enough since dentists recommend around 60 seconds of flossing per day. You also don't need to recharge this unit, as it runs on AC power. And for those concerned with tidiness, the tips can be neatly stored in the reservoir's cover.
Some Waterpik flosser reviews complain it takes up a lot of space and makes a quite a bit of noise, but most consumers report they are happy with their purchase. One says:
“This is my first water flosser. So far I love it. It’s easy to use and cuts maintenance time so I can get out the door or to bed. I wanted to post pics so you to see the size of the unit as I couldn’t really tell the space utilization. It’s compact and blends in.”
If you want the best Waterpik for braces, implants, braces and periodontal pockets, this water flosser model has it all. In fact, we even feature it in our article on the best Waterpik for tonsil stones.
Waterpik Ultra water flosser
If you are attracted to the Aquarius but are looking for something a bit more affordable, consider the Waterpik Ultra Water Flosser. This flosser is an earlier model than the Aquarius, and it has a bit bulkier design and doesn't look as modern.
That being said, it has plenty of functions, such as 10 pressure settings that are easily adjusted by a dial, and a convenient push-to-stop water flow button on the handle. It also has seven tips: three classic jet tips, a toothbrush tip, a plaque seeker tip, an orthodontic tip and a periodontal pocket tip.
It doesn't, however, have a 30-second pacer, nor does it have a hydro-pulse massage mode.
One reviewer sums up their experience by saying:
“We’ve been using these types of products for many years. They improved it with more hand control features, a stronger lid and a smaller water tubing coil that retracts better. We love these additions.”

Waterpik Cordless Express
If you're looking for an affordable, straightforward Waterpik model that you can take with you on the go, then this may be the Waterpik for you. The Cordless Express is one of the best cordless Waterpiks for a variety of reasons:
- Convenient: This Waterpik water flosser was designed for use anywhere, in small bathrooms, in the shower, and while traveling.
- Proven to work: It's accepted by the American Dental Association and shown to remove up to 99.9% of plaque where used.
- Time-saving: You only need 1 minute per day to improve your gum health.

“We purchased it for my stepdaughter who has braces. It works amazing and we don’t have to worry as much if she’s getting all. Doesn’t need to be charged too often and the refill is so quick and easy.”
Waterpik Sidekick Portable water flosser
The Sidekick is one of the newest Waterpik models and by far the most stylish. This sleek water flosser features a compact form and a water-resistant travel and storage case that allows you to take it with you wherever you go.
It's got some other outstanding benefits too:
- Full-sized power: This Waterpik may be lean, but it performs as well as any of the most powerful countertop models.

- New stylus tip: Integrated classic tip with swivel handle makes it easy to reach every corner of your mouth.

You may also be wondering can a Waterpik damage gums – the short answer is no, as long as you use it properly.
