Steps
Gently insert the brush head into the body of the
toothbrush. Between the casing and the head there should
be a small gap for the normal operation of the nozzle.
To prevent spattering of the toothpaste, apply a small
amount of paste to the brush head before use. (An
ultrasonic toothbrush saves more toothpastes than an
ordinary toothbrush)
Wash the brush head with water and place it in the mouth,
switch on the brush to start cleaning.
Slowly move the bristle at an angle of 45 ° along the gum
line for proper tooth brushing.
