Which of the following is a mechanical method of plaque control?

Mechanically removing plaque means physically dislodging and wiping away the biofilm from the tooth surfaces, not just altering it chemically. A manual toothbrush does this most clearly: the bristles, with brushing action, scrub and disrupt plaque so it is physically wiped away from teeth. Mouthwash acts mainly as a chemical agent, reducing bacterial load or neutralizing acids, but it doesn’t remove plaque by brushing. Fluoride toothpaste delivers fluoride for remineralization and caries prevention—the primary benefit is chemical—although brushing with toothpaste aids cleaning, the key effect described is chemical. Flossing also removes plaque mechanically between teeth, but in this context the classic example of a mechanical plaque-control method highlighted is brushing with a manual toothbrush.
