Fluoride is commonly used in toothpaste because it contributes to bone and teeth formation. Which mineral is this?

• A. Fluoride
• B. Calcium
• C. Potassium
• D. Sodium

Answer: (A)

The mineral at work in toothpaste that helps teeth form and stay strong is fluoride. Fluoride strengthens enamel by aiding remineralization after acid exposure and by forming a more acid-resistant mineral called fluoroapatite in the tooth structure. This is why fluoride is specifically added to toothpaste for dental health. Calcium is a major component of bone and teeth, but in the context of toothpaste, fluoride is the mineral linked to the protective effect on enamel. Potassium and sodium are electrolytes and do not play the primary role in enamel formation or cavity prevention.
