Sonic electric toothbrushes vibrate 30,000 times per minute or more, which in turn dislodges plaque, bacteria, and food particles. Oscillating electric toothbrushes spin 360 degrees up to 5,000 times per minute, and the constant rotation in an isolated area is considered to be more effective at blasting away buildup than sonic models.
