Caries may be partially controlled by decreasing the solubility of enamel and dentin in weak organic acids through treatment of the affected parts with silver nitrate solution.
Enamel, after exposure to 10 percent silver nitrate for one hour, becomes more resistant to the action of weak organic acids. Silver apparently combines with inorganic as well as organic materials in enamel.
