Why is toothpaste mildly basic?
Answer and explanation
Correct answer: To reduce acids in the mouth
Food particles and bacterial activity can produce acids in the mouth. A mildly basic toothpaste helps neutralise or reduce these acids, limiting their harmful action on tooth enamel and helping prevent decay. Therefore option A is correct. Toothpaste is not intended to make teeth sour, convert saliva into gas, or transform teeth into metal; those choices do not describe acid-base protection.
