PROBLEM TO BE SOLVED: To electrically prevent the onset of dental caries through diminishing electrical potential difference present in the oral cavity. SOLUTION: A method for preventing the onset of dental caries is provided, including the following process: both the endothelia and cuticles of the oral cavity are installed with polarizable anodes using a carbonaceous material to diminish the electrical potential difference between the teeth and gingiva to inhibit dissolving by electrolytic dissociation calcium phosphate as the main component of the teeth. In the method, as material for the electrodes, a carbonaceous material such as active carbon, bone charcoal, charcoal, graphite or carbon black is preferable; and it is a preferable method for installing the electrodes that, for the endothelia of the oral cavity, a flexible resin compound filled with powdery carbonaceous material is installed in the mouth, while for the cuticles of the oral cavity, a sheet-like carbonaceous electrode is installed on the cheek or underjaw; and negative electric charges are generated in the oral cavity through electric double layer to diminish the electrical potential difference in the oral cavity of 100-500 mV in the non-installed case to 100 mV or less to make the electrochemical reactions among the teeth and between the teeth and gingiva slower.
