Proper nutrition means eating a balanced diet so your body can get the nutrients needed for good health. Every day, your body renews itself, building new muscle, bone, skin and blood. The foods you eat provide the building blocks for these new tissues. If your diet is low in the nutrients your body needs, your mouth may have a more difficult time resisting infection.
If children do not eat a balanced diet, their teeth may not develop properly. In order for them to develop strong, decay-resistant teeth, children need a balanced diet with emphasis on calcium, phosphorous and proper levels of fluoride.
