Your Questions About Water Flossers Answered
What is the best water flosser?
If you’re ready to ditch the string and upgrade to a water flosser, my advice is to keep things simple. Ignore the fussy countertop models and go handheld with the Ordo Hydro Sonic. It hits the sweet spot between price, performance and design, with a decently sized 260ml tank, USB-C charging and a trigger button that makes it the least messy water flosser for newbies.
How I tested and selected the best water flossers
To separate the water pistols from the water cannons, I swapped my string floss for these devices over a period of several weeks, giving me plenty of daily flossing sessions to judge exactly how they perform. I tested each device against the daily realities of stubborn food debris, and my particularly tricky back molars (which my dentist has been telling me off about even since I got my wisdom teeth yanked out).
Can a water flosser completely replace string floss?
According to Dr Thakrar, a water flosser is a fantastic alternative for people who otherwise absolutely hate (and therefore avoid) traditional flossing. “Some studies suggest water flossers can remove similar levels or even slightly more plaque than string,” he adds. However, string floss still provides a physical “scraping” action that is highly effective for very tight gaps between teeth.
Are water flossers good for sensitive gums or braces?
Absolutely. Dr Thakrar explains that “the pressurised stream of water can reach areas around brackets, wires, bridges and implants that are often difficult to access with traditional floss”. Because they require less manual dexterity, they’re also great for anyone with arthritis or mobility issues.
What features should I look for when buying a water flosser?
To ensure you’re getting an effective clean, Dr Thakrar advises looking for “a model with multiple pressure levels so users can start gently and increase gradually.” He also recommends models with “pulsation technology,” noting that “pulsating streams improve plaque disruption compared with a continuous jet.”
How do you use a water flosser?
If it’s your first time, keep a towel close at hand. As Dr Thakrar notes, “water flossers can be a little messy at first and may take some time to get used to.” The golden rule is to always lean over the sink and keep your lips partially closed around the nozzle – you want to let the water flow freely out of your mouth.
