Toothache

Children are commonly told that too much
candy and sugar causes cavities. While sugar
promotes the creation of acid which breaks
down teeth, acid breakdown is the reason for
cavities. Sugar is not the only food that promotes
acid; food and drinks such as citrus and
wine also promote acid breakdown.
