How to Use a Waterpik
A water flosser doesn't replace your toothbrush or traditional flossing. You still need to brush your teeth twice a day, but you can use the water flosser before or after brushing. It's important to note, though, that studies have shown that flossing before brushing removes more plaque.
Fill your water flosser's reservoir with lukewarm water, then put the flosser tip in your mouth. Lean over the sink to avoid a mess.
Turn it on, and then it's time to clean. Hold the handle at a 90-degree angle to your teeth and spray. Water comes out in steady pulses, cleaning between your teeth.
Start at the back and work your way around your mouth. Focus on the top of your teeth, the gum line, and the spaces between each tooth. Remember to get the back of your teeth, too.
The process should take about 2 minutes. When you're done, empty any extra water from the reservoir so bacteria don't grow inside. Sharing a single Waterpik can raise the chance of spreading bacteria between users. But replacing the nozzle before sharing can lower this risk.
