Which of the following dietary items is most likely to cause dental erosion?
Show answer and explanation
Correct answer: D. Tea with lemon
- A. Incorrect. Almond butter is essentially neutral in pH and is not erosive.
- B. Incorrect. Cheese is actively protective: it raises plaque pH, stimulates salivary flow, and supplies calcium, phosphate and casein.
- C. Incorrect. Milk has a near-neutral pH and its calcium and phosphate content make it non-erosive.
- D. Correct. Erosion is caused by acid of non-bacterial origin. Tea — particularly with lemon or other citrus additions — has a low pH and directly dissolves enamel.
