Abstract
An oral care agent delivery device is provided which comprises a permanently deformable backing layer, an oral care layer, and a non-woven binding material with a first part that is substantially invested in the oral care layer and a second part that is substantially invested in the backing 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 comprises at least one oral care agent and at least one hydrophilic polymer. When hydrated, the oral care layer has an adhesiveness relative to the surface of a user's teeth that is sufficient to retain the device on the user's 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.
