An instrument that is electrically-powered from the mains (AC-powered) via a transformer and designed to be used by a person to brush clean their teeth and gums (i.e., remove plaque, tartar, stains). It typically consists of a proximal handle and distal head to which is attached two or more rows of bristles (e.g., nylon) grouped in separate tufts, in rows, or evenly distributed. The device provides automated bristle movement (e.g., rotary or vibratory) intended to augment brushing, and is typically used with toothpaste; it is normally available [non-prescription] over-the-counter (OTC). The toothbrush head may be exchangeable. This is a reusable device.
