A composition and method for self-cleaning of the teeth and mouth using a source of light in the visible range in conjunction with a photosensitive liquid oral hygiene composition possessing a broad absorption spectrum in the visible range. The composition and method selectively eliminates harmful bacteria by use of a photosensitive agent and a light source. The composition also includes resistive elements to protect the photosensitizers from the degrading effects of blood serum, saliva, and other materials located naturally within the oral cavity. The method involves the use of a light-providing dental device to activate a photosensitive agent and destroy harmful bacteria in the oral cavity. It prevents or deters oral diseases, inflammations, and infections.
