ABSTRACT OF THE DISCLOSURE A dental hygiene device having a body with an inserting portion disposed to be inserted into a mouth and to respond to water and/or sputum and an n-type semiconductor accommodated in the body and adapted for causing a photocatalyst reaction as being at least partially inserted into the mouth to come into contact with the water and/or sputum, the n-type semiconductor being formed as a thin layer on a surface of a conductive member. And, a dental hygiene device having a body with an inserting portion disposed to be inserted into a mouth and to respond to water and/or sputum and an n-type semiconductor accommodated in the body and adapted for causing a photoelectric chemical reaction as being at least partially inserted into the mouth to come into contact with the water and/or sputum, a direct current source disposed in the body and connected to the semiconductor and a good conductor disposed in the body and connected to the semiconductor. As the inserting portion is inserted into the mouth, the n-type semiconductor, the direct current source and the good conductor act together with to constitute a circuitry.
