    Abstract: Tooth-whitening films comprising a hydratable polymer and a whitening agent are disclosed in which the films have a hydrophobic coating on one surface and a tooth-adherent coating on the opposing surface. Flavorings can also be included in the hydratable polymer portion of the film or in either the hydrophobic coating or the tooth-adherent coating. Tooth-whitening methods that use the films are also disclosed. The hydratable polymer preferably is a polyethylene oxide.
