Frequently Asked Questions
How do I use the Sonic Flo?
Fill the reservoir, choose a mode, lean over the sink and aim along the gumline and between teeth. Glide tooth-to-tooth; keep lips slightly closed to control spray.
Is it suitable with braces, retainers, implants or bridges?
Yes. Use a gentler mode around sensitive areas and angle the tip to flush around brackets, wires and implant/bridgework. If you've had recent surgery, follow your clinician's guidance.
How often should I water floss?
Most people use it once daily, ideally in the evening before brushing (or after, if you prefer the fresh finish). Consistency matters more than order.
Which mode should I choose?
Start on a gentler mode if you have sensitivity and increase as comfortable. Use higher pressure for deeper interdental flushing once you're used to the feel.
Can I use mouthwash in the flosser?
You can add a small amount of alcohol-free mouthwash diluted with water. Avoid thick solutions or oils that can clog the system; always rinse the reservoir after.
Is it messy?
It's easy once you get the hang of it. Lean over the sink, keep your lips slightly closed and let the water flow out as you move along the gumline.
How do I clean the device and reservoir?
Empty and rinse the reservoir after use, then leave it to air dry. Wipe the exterior with a soft, damp cloth - no abrasives or solvents.
How often should I replace the nozzle/tip?
Typically every 3-6 months, or sooner if the tip becomes worn or damaged.
Is it safe for sensitive gums or gum disease?
Use a gentler mode and consult your dentist if you're undergoing treatment. Water flossing can complement professional advice - not replace it.
Can I travel with it?
Yes - the cordless design is travel-friendly. Empty the reservoir before packing and protect the tip in transit.
Does the Sonic Flo replace string floss?
It's an effective alternative for many people and a great adjunct to brushing.
