A battery-powered instrument designed to brush clean the teeth and gums. 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 head includes a light-activated semiconductor [e.g., a titanium (Ti) rod] that releases negative ions intended to disintegrate dental plaque. The device provides automated bristle movement (e.g., rotary or vibratory) intended to augment brushing and is used with toothpaste; it is normally available [non-prescription] over-the-counter (OTC). The toothbrush head may be exchangeable. This is a reusable device.
