SONIC TECHNOLOGY The high frequency vibration of the sonic electric toothbrush creates a fluctuating cleaning force. Sonic toothbrushes generally vibrate at 24,000 – 40,000 strokes per minute. In comparison, oscillating electric toothbrushes rotate at around 1,300 – 8,800 strokes per minute. Compared to traditional toothbrushes, sonic electric toothbrushes are better suited for scientific up and down brushing.
