The condition that damages tooth enamel is related to which of the following?

Answer and explanation

Correct answer: pH in the mouth falling below 5.5

Tooth enamel is mainly mineral in nature and begins to dissolve when acids lower the pH in the mouth below about 5.5. Bacteria can act on food residues and produce acids, creating this condition. A pH of 7 is neutral and is not the critical acidic condition stated here. Water alone and the absence of bacteria do not explain enamel damage. Thus, option A is correct.
