Animal consumable dental hygienic device, comprising: body with an exterior surface and an interior cavity, and sized to be bitten by animal. Exterior surface defines projections. Recesses extend inward from the exterior surface. Each recess has dental-hygienically active dimensions allowing a tooth to penetrate therein such that material surrounding the recess frictionally engages an outer surface of the tooth and scrapes the tooth to remove dental plaque. Projections are positioned, dimensioned, shaped and structured to be dental- hygienically active when the animal bites the body, allowing the tooth of the animal to be adjacent to at least one projection when the animal bites the body, such that a projection frictionally engages at least one of the outer surface of the tooth and gums of the animal during biting of the body by the animal.
