Why is very low pH in the mouth dangerous for tooth decay?

Answer and explanation

Correct answer: Low pH increases acidity which damages tooth enamel

The pH scale shows acidity inversely: a lower pH means a greater concentration of hydrogen ions and a more acidic environment. Acids produced by bacteria can react with and dissolve minerals in tooth enamel, especially when the mouth remains acidic for a long time. This softens the enamel and promotes cavities. Hence A is correct; low pH is not basic, does not make teeth metallic, and is not harmless.
