Which recommendation might you make to Aaron to reduce his caries risk?

• A. Brush after every snack
• B. Replace soda with water
• C. Drink the lemon-lime soda with a meal rather than between meals
• D. Use a straw when drinking soda

Answer: (C)

The main idea here is that when sugary, acidic beverages are consumed between meals, teeth endure longer exposure to sugars and acids, which accelerates acid production by bacteria and demineralization of enamel. Drinking the lemon-lime soda with a meal takes advantage of the body's natural saliva boost during eating and the mechanical cleansing from chewing. This helps buffer acids, wash away sugars more effectively, and shorten the time teeth are exposed to cariogenic conditions. So, even though the soda is still acidic, having it with a meal reduces the overall risk more than sipping between meals. Replacing soda with water would also lower risk, but the option about timing specifically targets how exposure occurs, making it a particularly impactful behavioral change. Using a straw offers only a minor, surface-level reduction in contact, and brushing after snacks, while helpful, carries enamel erosion considerations if done immediately after acidic intake.
