List some cariostatic foods and explain why these foods may provide protection against cavity formation

What will be an ideal response?

Certain foods, such as tart foods and sugar-free gum, may have cariostatic effects through increasing saliva flow, which results in increased oral clearance and an enhanced buffering capacity. Dairy foods, such as cheese, yogurt without added sugar, and milk increase the calcium and phosphorus concentrations in the oral cavity to buffer the pH of the saliva.
