• Please use the appliance together with toothbrush. It is hard to remove tartar or dental calculus attached to the tooth surface just by a water jet, so a toothbrush is required to brush the teeth. We recommend rinsing the inside of your mouth with the water jet after brushing your teeth.

• When you rst begin using the oral irrigator, you may experience slight bleeding of the gums even though your gums may be healthy. This is because your gums are receiving stimulation by the oral irrigator for the rst time. The bleeding should stop after one or two weeks of use. Bleeding that persists for more than two weeks may be indication of an abnormal condition of your gums, such as periodontal disease. In this case, stop using the oral irrigator and consult your dentist.
