How to Use
0.4-1mm
1. Make sure that the toothbrush head is installed in the same
direction as the front of the toothbrush handle, and make
sure there is a slight gap between the toothbrush head and
the handle (the gap is designed to prevent the toothbrush
head from colliding with the handle during high-frequency
vibration, so as to generate more power from the motor).
2. Wet the toothbrush head and squeeze a proper amount of
toothpaste onto the toothbrush head.
