Question

Quizplus · Accepted Answer

Fluoride is a mineral that has been proven to strengthen tooth enamel and prevent tooth decay. It helps replace lost minerals in the enamel and makes it more resistant to acid attacks from bacteria in the mouth. Abrasives may help remove surface stains but can damage the enamel if used excessively. Plaque is a sticky film of bacteria and food particles that can erode enamel if not removed through regular brushing and flossing. Protein is essential for healthy tooth structure but does not specifically strengthen enamel.
