Delivery systems for whitening teeth are provided. The delivery system includes a strip of material sized to cover a front surface of a plurality of teeth and a layer of a tooth whitening substance in contact with the strip of material. The tooth whitening substance includes a gelling agent and a whitening active selected from the group consisting of peroxides, metal chlorites, perborates, percarbonates, peroxyacids, hypochlorites, and combinations thereof. The delivery system further includes a release liner having a coating thereon, wherein the release liner exhibits less affinity for the tooth whitening substance than the tooth whitening substance exhibits for itself and for the strip of material.
