Once a child has developed tooth decay, he/she will require dental work. Fillings may be used to correct smaller cavities, and a full crown may be needed if the damage is extensive. This will prevent the bacteria from spreading.
A tooth that has decay throughout may have to be extracted because the bacteria can cause the secondary, or adult teeth, to develop abnormally. Pitting or staining in the adult teeth may occur if decay is severe enough in the primary teeth.
