Studies have shown that rotating-oscillating electric toothbrush heads, the type that quickly spin in a circle, require slightly less movement by the operator to gain a decent clean. This do not mean that the toothbrush will do all the work for you, but rather it refers to the fact that, with 360 degree turns, the toothbrush head does more concentrated cleaning compared to heads that only move side to side. Therefore, rotating-oscillation electric toothbrushes do not need to be moved side to side to gain a great brush, as you would do with one that has a head that moves side to side. They just need to be moved around the mouth to ensure all areas are being targeted.
