ABSTRACT:
There is provided a toothbrush where the dose of dentifrice used is controlled by the use of bristles of at least two different colors. When the bristles of one color are covered with a dentifrice the dose will be within guidelines. In addition, the dentifrice and bristles of one of the colors can be the same to aid in controlling the dose of dentifrice. This will in turn limit the dose of fluoride and other components of a dentifrice.
