The American Academy of General Dentistry has reported that fasting or eating a strict vegetarian diet can lead to a deficiency of calcium, vitamin D, vitamin B-12 and protein. These nutrients are all important to maintain oral health. Regularly use a soft-bristled toothbrush, fluoride toothpaste and dental floss to prevent tooth erosion. Fruit diets have been popular, but the natural sugar from fruit can cause cavities. The acid in grapefruit, oranges, lemons and other citrus fruits can erode enamel.
Bananas are a particularly sticky, cavity-causing food.
Since fruits should be part of a varied and balanced diet, oral hygiene is especially important to keep teeth cavity-free. Avoid crash diets. A balanced diet rich in all major food groups, regular moderate exercise and good oral hygiene will keep your body trim and your smile bright. Watch this if baby's meals end with thrown food.
