Is Water Flossing Messy?
Compared to string floss, water flossing is easier and doesn't require you to put your hands in your mouth or deal with used string floss.
The correct technique is the key. Unlike string floss, you don’t need to look in the mirror or hold your mouth open wide.
To use a water flosser, place the flosser tip in your mouth, close your lips most of the way, and lean over the sink. Then turn the power on. As you floss along the gumline and between your teeth, allow the water to empty from your mouth into the sink.
