ABSTRACT:
An oral hygiene system includes a method of removing plaque from teeth and gums by brushing the teeth with a plaque-disclosing dentifrice composition including a dye which will differentially stain plaque according to the organizational structure of the plaque, correlating the observed color of the plaque to the plaque structure, and brushing to remove the plaque structure so identified. The system also includes a toothbrush having a head and a handle, where the head has bristles with their freestanding end in a square pyramidal shape with sides having a slope corresponding approximately to buccal and lingual contours of a tooth.
