Sonic Electric Toothbrush 1 article

A Sonic Electric Toothbrush drives its brush head with high-frequency side-to-side or sweeping motion, contrasting with the small oscillating-rotating pattern used by another major powered-brush design. The user guides the moving bristles around teeth and gingival margins while the motor supplies repeated strokes; timers, pressure sensing or app connectivity may be added separately. The term refers specifically to sonic-style powered motion. It should therefore be distinguished from electric toothbrushes based on oscillation, even though both belong to the wider powered-brushing category.
