Abstract
Abstract A toothbrush having a removable brush which includes dentifrice applied to the bristles of the brush. An elongated base is removably mounted to one end of a toothbrush handle. The handle may be disposable and reusable. A plurality of upstanding straight flexible bristles extend upright from the top surface of the base and are arranged in a plurality of spaced apart rows. A plurality of flexible loop-configured bristles are fixedly mounted to the base and extend upwardly from the top surface thereof being arranged in lines interspaced between the rows of straight bristles. Each loop-configured bristle defines and encloses an area in which dentifrice is positioned. In one embodiment, adhesive is provided to secure the base to the handle whereas in another configuration, a pair of opposed clips mounted to the handle are removably engaged with the opposite ends of the base.
