Installing the Toothbrush Head
Ensure the toothbrush head is installed in the same direction as the front of the toothbrush handle. A slight gap (0.4-1.0mm) should remain between the toothbrush head and the handle. This gap is intentional, designed to prevent collision during high-frequency vibration and to generate more power from the motor.
