A sticky film of bacteria, called plaque, constantly forms on teeth. When sugar and starch from food and drinks combine with plaque, an acid is produced. The acid attacks tooth enamel. Repeated acid attacks break down enamel and eventually result in tooth decay. Sugar and starch are present in many foods, even fruits and vegetables. Although these foods can provide the nutrients children need, frequent between-meal snacks expose teeth to acid attacks. This is the reason the Smile Shoppe Team highly recommends that you wait at least two hours in between snacks/mealtime for your child.
