Direction: Place the brush bristles on the gumline, then press and brush gently along the direction of teeth. Brush downward for upper teeth and upward for lower teeth. All aspects of your teeth have to be brushed. The same area needs to be repeatedly brushed.
Caution:1. Please do not clean the toothbrush with acid bleach or hot water to prevent the bristles from shedding or deforming. 2. Rinse the brush thoroughly after each use, and store it in a cool and dry place. 3. Please replace the toothbrush every one to three months. If the bristles become bent or tilted, please replace in time. 4. Keep the water temperature below 50C.
