1. An oral care article comprising:
a) a solid hydrophobic delivery carrier in the form of a strip having a length and a width forming a first surface and having a thickness extending from the first surface to a second surface; and
b) solid hydrophilic particles embedded in the solid hydrophobic delivery carrier partially below the first surface and partially at or above the first surface of the solid hydrophobic delivery carrier, wherein the solid hydrophilic particles comprise an active agent for oral care comprising an anti-calculus agent, an anti-caries agent, an antimicrobial agent, a dentinal desensitizing agent, a bleaching agent, or combinations thereof,
wherein a concentration of the active agent at the first surface is greater than a concentration of the active agent at the second surface.
