4. Vitamin C
Eating food high in vitamin C is beneficial to teeth. Fruits like citrus, kiwi, and strawberries reduce the amount of bacteria in the mouth, increase gum health, and help prevent gingivitis or gum disease.

5. pH
Dairy products like cheese counteract the acids caused by plaque, raising the pH of the mouth and preventing the spread of tooth decay. Encourage your kids to indulge in these snack-friendly foods.
