A tooth whitening appliance includes an applicator having a soft moldable core covered by a plastic film membrane. The contours of buccal surfaces of target teeth to be whitened are impressed into the applicator by applying lateral pressure. A layer of tooth whitening preparation is deposited on the impressions formed in the applicator and the applicator is repositioned against the buccal tooth surfaces for the administration of the tooth whitening preparation. The applicator core is soft and moldable preferably at or below body temperature. The membranes support the applicator in reduced thickness impression areas. The applicator core may be optionally preloaded with tooth whitening preparation.

Having thus described the invention, there is claimed as new and desired to be secured by Letters Patent: 1. A tooth whitening appliance comprising an applicator and a carrier, the applicator being positioned on the carrier, the applicator having a core, the core comprising a formative wax capable of receiving a dental impression, the wax being soft and moldable at or below body temperature, the applicator having a buccal face and a lingual face, at least one of the faces being overlaid with a plastic film membrane, the carrier comprising a panel and a transverse ledge extending from the panel, the ledge having a free distal edge, the panel and the ledge defining a substantially "L" shaped transverse cross section throughout the carrier. 2. A tooth whitening appliance for the administration of a tooth whitening preparation as constructed in accordance with claim 1 wherein the lingual face and the buccal face of the applicator are overlaid with a plastic film membrane. 3. A tooth whitening appliance in accordance with claim 1 wherein the panel is semi-cylindrical. 4. A tooth whitening appliance as constructed in accordance with claim 1 wherein the applicator core abuts the carrier panel. 5. A tooth whitening appliance for the administration of a tooth whitening preparation as constructed in accordance with claim 1 wherein the plastic film membrane comprises a thermoplastic selected from the group consisting of low density polyethylene, polyvinyl chloride and polyvinylidene chloride. 6. A tooth whitening appliance for the administration of a tooth whitening preparation as constructed in accordance with claim 1 wherein the lingual face of the applicator includes impressions of buccal surfaces of the target teeth, the appliance being positioned in an oral cavity with the impressions being registered with the corresponding buccal surfaces, a layer of tooth whitening preparation being positioned between the buccal surfaces and the corresponding surfaces of the impressions. 7. A tooth whitening appliance for the administration of a tooth whitening preparation as constructed in accordance with claim 6 wherein the layer of tooth whitening preparation is positioned between the buccal surfaces and the plastic film membrane. 8. A tooth whitening appliance for the administration of a tooth whitening preparation as constructed in accordance with claim 1 wherein the plastic film membrane overlies the lingual face of the applicator, the plastic film membrane including perforations, the perforations carrying a tooth whitening preparation. 9. A tooth whitening appliance for the administration of a tooth whitening preparation as constructed in accordance with claim 1 wherein the core carries a tooth whitening preparation, the tooth whitening preparation being released from the core when the applicator receives impressions of the buccal surfaces of the target teeth. 10. A tooth whitening appliance for the administration of a tooth whitening preparation as constructed in accordance with claim 9 wherein the tooth whitening preparation is carried in a plurality of pockets formed in the core. 11. A tooth whitening appliance for the administration of a tooth whitening preparation as constructed in accordance with claim 10 wherein the plastic film membrane overlies the lingual face of the applicator, the plastic film membrane including perforations. 12. A tooth whitening appliance for the administration of a tooth whitening preparation as constructed in accordance with claim 9 wherein the core carries a plurality of microcapsules, the tooth whitening preparation being released from the microcapsules when the applicator receives impressions of the buccal surfaces of the target teeth. 13. A tooth whitening appliance for the administration of a tooth whitening preparation as constructed in accordance with claim 12 wherein the plastic film membrane overlies the lingual face of the applicator, the plastic film membrane including perforations. 14. A method of whitening teeth utilizing a tooth whitening preparation, the method comprising the steps of: a) providing an appliance having a carrier with a substantially "L" shaped transverse cross section and an applicator having a core with rheological characteristics suitable for implementation as a dental impression material, b) adhering a plastic film membrane over at least one face of the applicator, c) obtaining in the one face of the applicator impressions of buccal surfaces of selected target teeth by inserting the carrier and the applicator in an oral cavity and applying lateral pressure against the carrier to force the applicator against the buccal surfaces of the selected target teeth, d) removing the carrier and applicator from the oral cavity after the impressions have been taken, e) separating the carrier from the applicator, and f) administering the preparation to the buccal surfaces by covering the buccal surfaces with the applicator and with a layer of preparation positioned between the buccal surfaces and the impressions formed in the one face of applicator. 15. A method in accordance with claim 14 wherein the step of administering the preparation includes applying a layer of preparation to the impressions of buccal surfaces formed in the applicator and thereafter covering the buccal surfaces of the selected target teeth with the applicator. 16. A method in accordance with claim 14 wherein the layer of preparation is positioned between the buccal surfaces and the plastic film membrane. 17. A method in accordance with claim 14 wherein the applicator includes two faces and the step of overlying a plastic film membrane comprises overlying a plastic film membrane over each face of the applicator. 18. A method of whitening teeth utilizing a tooth whitening preparation, the method comprising the steps of: a) providing an appliance having a carrier with a substantially "L" shaped transverse cross section throughout and an applicator having a core with theological characteristics suitable for implementation as a dental impression material, b) adhering a plastic film membrane over at least one face of the applicator, c) obtaining in the applicator impressions of buccal surfaces of selected target teeth by inserting the applicator in an oral cavity and applying lateral pressure against the carrier to force the applicator against the buccal surfaces of the selected target teeth, d) positioning a layer of preparation between the buccal surfaces and the impressions formed in the applicator. 19. A method of whitening teeth utilizing a tooth whitening preparation in accordance with claim 18 wherein the preparation is carried in the applicator and the membrane is perforated, the step of positioning including: i) extruding the tooth whitening preparation through the perforations.
