摘要:
An oral care agent delivery device is provided which comprises a permanently deformable backing layer (170), an anchor layer (180) overtop the backing layer, and an oral care layer (190) overtop the anchor layer. The device is sized to fit over a plurality of teeth in an upper or lower dental arch of a subject. The oral care layer (190) comprises at least one oral care agent and at least one hydrophilic polymer. The oral care layer is in contact with the anchor layer and forms an adhesive bond with the anchor layer however, the oral care layer is minimally invested in the anchoring layer. When hydrated, the oral care layer has an adhesiveness relative to the surface of a users teeth that is sufficient to retain the device on the users teeth when placed thereon. The device can also have an oral care agent which is activated on hydration of the oral care layer, or an oral care layer which releases the oral care agent over time.
