Modern smart toothbrushes have a vibration-sound principle of operation. In sonic toothbrushes, the brush head vibrates at a high frequency of about 40,000 rpm and, upon contact with the teeth, generates sound waves that help clean teeth in hard-to-reach places, whiten the teeth and massage the gums. Some sources mistakenly call these toothbrushes “ultrasonic.”
