Tooth decay increases when the acidity value in the mouth becomes too low. What is the main reason?

Answer and explanation

Correct answer: Acids weaken and damage the outer enamel of teeth

The governing concept is pH and the action of acids on tooth enamel. Bacteria use sugars and food particles to produce acids, lowering the mouth’s pH. When the pH becomes sufficiently low, the mineral-rich enamel begins to lose minerals and becomes weaker, increasing decay. Therefore, option A is correct. Bases do not immediately dissolve teeth, salt does not make teeth metallic, and ordinary water is not the main cause.
