Frequently Asked Questions
Can a water flosser replace string floss?
They clean in different ways, so many people use a water flosser alongside brushing and string floss. If you are not sure what suits you, ask your dentist.
Does it make a mess at the sink?
Lean well over the sink, place the tip in your mouth before you switch it on, and let the water run out of your mouth. Most of the mess comes from turning it on too early.
Which mode should I start with as a first-timer?
Gentle. Once the sensation feels familiar, try Standard or Powerful. Pulse and Massage are there when you want a different feel along the gumline.
Can I use it in the bathroom without worrying about splashes?
Yes. It is IPX7 waterproof, so splashes and rinsing under the tap are fine. Dry the charging port before you plug it in.
Will it last through a trip?
It is cordless, charges over USB-C and gives 50+ minutes of runtime on a full charge, so it packs easily. Airline rules for lithium-battery devices vary, so check yours before you fly.
