Eating Children should receive a balanced diet daily to help support proper tooth development. This balanced diet includes: Food from the major food groups. Limiting consumption of sugar/starch foods. Limiting between meal drinking and snacking. Children should be encouraged to have breakfast to avoid increased snacking between meals during the day. Risk of cavities increases when sugar is consumed between meals. Snacks have the highest sugar content of any meal. Avoid foods and beverages high in acidic content. They weaken tooth structure and lead to increased cavities.
