Which of the following foods causes erosion on teeth?
Show answer and explanation
Correct answer: D. Tea
- A. Cheese is actually CARIOSTATIC and anti-erosive — it raises oral pH and provides calcium and phosphate for remineralization.
- B. Almond butter is not acidic and does not cause dental erosion. Its pH is near neutral.
- C. Milk has pH around 6.3-6.8 and contains casein and calcium — it is not erosive and may be protective.
- D. Tea (especially herbal/fruit teas) has an acidic pH (often 3.0-4.5) that can cause dental erosion with frequent consumption. Fruit teas can have pH as low as 2.7. While black tea has some anti-bacterial properties, its acidity makes it erosive.
