A photocatalysis process toothbrush comprising a handle with a grip at a proximal end and a head at a distal end thereof. The head has at least one group of bristles and at least one blue light emitter is provided on an upper surface of the head for emitting blue light in a direction generally parallel to the bristles. At least one blue light source is provided for radiating blue light, in a wavelength band between 420 nm to 480 nm, and a power source is provided for energizing the at least one blue light source. The blue light is at least one of modulated emission with an average optical output power level of less than 5 watts.
