Most people know brushing teeth for 3 min is good for their dental health. Therefore, this toothbrush helps people recognize 3 minutes easier, which means this tooth brush detects the body temperature and changes it's color by using the chemical pigment, when grabbed by a person. When the color turns completely another color, it signals that the person has been brushing teeth for 3 min.
