Acids produced by bacteria in the mouth after eating can damage tooth enamel. Which habit is most suitable for reducing this damage?

Answer and explanation

Correct answer: Brushing teeth with a basic toothpaste

Oral bacteria act on sugars to produce acids, which lower the pH and can increase enamel erosion. A basic toothpaste helps neutralise the acid. In contrast, sugary drinks provide more sugar for bacterial acid production, and acidic fruit juices can increase acidity in the mouth.
