For high-risk patients, which type of beverage is recommended to minimize caries risk?

• A. Non-sugary drinks
• B. Sugary drinks
• C. Sugary carbonated drinks
• D. Alcoholic beverages

Answer: (A)

Minimizing exposure to fermentable carbohydrates is key to lowering caries risk. When patients at high risk drink beverages without fermentable sugars, there’s little substrate for oral bacteria to metabolize into acids, so plaque pH stays higher and enamel demineralization is reduced. Non-sugary drinks, like plain water or unsweetened beverages, hydrate without feeding cariogenic bacteria, making them the best choice for lowering caries risk. In contrast, sugary beverages supply sugars that bacteria convert to acids, sugary carbonated drinks add both sugar and acid, and alcoholic beverages can promote dry mouth and sometimes contain sugars themselves, all of which can increase caries risk. So choosing non-sugary drinks helps protect against caries while other options pose higher risk.
