Sonic toothbrushes for white and clean teeth
With a sonic toothbrush, the brush head swings back and forth with very fast movements. Depending on the model, up to 40,000 oscillations per minute are generated by an electric transducer. Although the cleaning is done purely by the bristles, it is more thorough than with conventional electric toothbrushes. Therefore, more plaque will be removed. Due to the high frequency of the movements, the better cleaning performance is also noticeable and one is less tempted to exert high pressure while brushing the teeth.
