The main difference between an electric vs a sonic toothbrush is that electric toothbrushes rotate, while sonic toothbrushes vibrate.
Electric toothbrushes typically rotate at 1,300-8000 strokes per minute, while sonic toothbrushes like buzzz can vibrate at up to 28,000 strokes per minute. buzzz doesn’t just clean the plaque off with its side-to-side vibrations. It also cleans hard-to-reach areas by emitting sonic pulses that disrupt the fluid built up between your teeth.
