While I don’t often reminisce about my days with “gappy teeth” before starting Invisalign, I now realize how easier it was for food and plaque to avoid getting trapped in those spaces—a fact I didn’t appreciate at the time. Flossing my teeth prior to braces was straightforward but ultimately ineffective, akin to attempting to clean a tunnel with a pipe cleaner.

Now that my gaps are closed, my water flosser has become an essential tool in my oral hygiene routine. This device uses a powerful stream of water to clear food particles and debris between teeth, leaving my mouth feeling invigorated.
“Many individuals are aware of the importance of flossing, yet it remains one of the most neglected aspects of daily dental care,” states Dr. Johannes Jacobs, the founder of Jacobs & Associates Dental Office. “Patients who find traditional flossing challenging often see significant improvements in their gum health when they switch to water flossers.”
Most dentists I consulted prefer traditional floss or interdental brushes, like those made by TePe, but they unanimously agree that utilizing a water flosser is certainly better than neglecting flossing altogether.
“While water flossers lack the scraping action provided by standard string floss, they offer greater accessibility and comfort,” explains Jacobs. “For many patients, this ease of use is crucial. If traditional flossing is painful, frustrating, or impractical due to dexterity challenges or dental appliances like braces, it often leads to avoidance.”
“Water flossers are user-friendly, making them suitable for children and older adults alike. I frequently recommend them—not as a complete substitute for floss, but as a viable option for those who currently do not floss.”
In recent months, I have been rigorously testing various water flossers. Here are my top picks.
Best overall water flosser: Waterpik Ultra Professional
Best budget option: Operan Cordless Oral Irrigator
Best cordless model: Philips Sonicare Cordless 3000
To start, I have 32 teeth, which is typical for adult humans. This may seem like an unusual detail, but it is an important factor when evaluating water flossers. After undergoing Invisalign treatment, my teeth are now closely aligned, presenting a more challenging scenario for testing various flossing devices.
Moreover, with over a decade of professional experience in testing consumer technology, I have previously evaluated top electric toothbrushes, which lends credibility to my assessment of water flossers.
The testing process involved using one water flosser after another, treating my teeth with the kind of meticulous care usually reserved for the frantic hours leading up to a dental appointment. Each flosser was utilized multiple times, exploring different heads and settings while noting usability features and overall mouth comfort. Additionally, I conducted some unconventional tests to verify manufacturers’ claims, such as measuring water tank capacities and assessing the power of the water jet.
While I wouldn’t advise replicating my more unscientific methods—such as firing water jets across a room—if you do decide to attempt such tests, ensure you are in a non-carpeted area and keep pets secured.
Water flossers were provided by various manufacturers, including Oral-B, Panasonic, Ordo, Waterpik, and Philips, and after testing, the devices were donated to Bridge2Aid, an organization focused on oral health education.
Countertop water flossers appear to be declining in popularity, and I managed to acquire just one for this review. The Waterpik Ultra Professional showcases why this trend is regrettable, offering the largest water reservoir and flexibility that cordless models often lack.
Why we appreciate it: Unlike cordless options, the water reservoir remains stationary on your countertop, allowing for easier maneuverability while cleaning your teeth. The 650ml tank is always accessible, ensuring a continuous water supply during use—unlike some cordless models, which may run low when reaching the back of the mouth.
Additionally, it features ten pressure settings ranging from 10PSI to 100PSI, enabling users to select their preferred pressure level. The flosser comes with seven interchangeable heads, including three standard jet tips, a plaque seeker, an orthodontic head, a Pik Pocket tip, and a toothbrush attachment.
However, the countertop design does have some drawbacks. It is not portable (dimensions: 11.9 x 9.7 x 26.3 cm), and taller individuals may find it cumbersome. Nevertheless, if space is available, I highly recommend this model.
Tank capacity: 650ml
Number of heads: seven (3 jet tips, plaque seeker, orthodontic head, Pik Pocket, toothbrush)
Pressure range: 10-100PSI
Waterproof: not specified
Charging: not applicable
Most cordless water flossers typically cost between £60 and £120, but the Operan model is significantly more affordable while still delivering impressive results.
Why we appreciate it: I initially suspected the Cordless Oral Irrigator’s low price would come with compromises, but that turned out to be unfounded. Its design is comfortable to hold, and it offers four distinct power settings with a gentle pulsing stream that effectively cleans teeth, even when positioned upside down.
