A system for providing an oral care agent to a tooth, the system comprising a first layer comprising the oral care agent; and a second layer configured to be spaced from a surface of the tooth by the first layer, wherein the first layer comprises a first solvent and is curable during or after its application, and wherein the second layer is a fluid comprising liquid carrier different from the first solvent, wherein the first layer comprises a first polymer matrix, the first solvent, and the oral care agent; and
wherein the second layer comprises a second polymer matrix and a second solvent different from the first solvent, the system being configured such that the first layer is dried/cured by evaporating the first solvent; and the second layer is dried/cured by evaporating the second solvent.
