Water flossers have been shown to be 5 times more effective at removing plaque between teeth. Research has shown that water flossers improve gum health better than traditional flossing. HOW TO USE Pour a capful of supersmile whitening pre-rinse into the flosser tank, then fill the rest of the tank with water. Select mode, `Low' is recommended for first-time use or those with sensitivity. Point the nozzle between teeth near the gumline, close mouth, and turn on. Keep the flosser nozzle pointed at the spaces between teeth and along the gumline to dislodge food particles and potential plaque. Then rinse. Do not swallow. After flossing teeth, brush.
