A tray-shaped dental treatment device includes a moisture-resistant barrier layer having a front side wall and a bottom wall, and a dental treatment composition. In addition, the tray-shaped dental treatment device includes at least one of the following anatomical features to enhance the fit of the device: (1) the bottom wall includes a plurality of cuts positioned to help the bottom wall better conform to abrupt changes in the diameters of a person's teeth where the bicuspids and canines meet, or (2) the bottom wall includes at least one V-shaped or U-shaped indentation configured to be inserted into the depression typically found along the top surfaces of a person's molars, or (3) the front side wall and bottom wall include radii of curvature that account for typical flaring of a patient's incisors.

What is claimed is: 1. A dental treatment system for use in applying a treatment composition to a person's teeth, comprising: a moisture-resistance barrier layer having a front side wall and a bottom wall, and that is adapted to be worn over at least a portion of a person's upper or lower dental arch without requiring customization prior to wearing, the barrier layer comprising a thin-walled, flexible membrane material that is adapted to at least partially conform to the person's teeth when placed over a patient's teeth to apply the treatment composition; said barrier layer comprising one or more anatomical features that facilitate the ability of the barrier to conform to the patient's teeth when worn for treatment; a support skeleton positioned adjacent to the barrier layer prior to placement over the patient's teeth so as to maintain the thin-walled flexible membrane material in a tray-like configuration to facilitate placement of the barrier layer when forming the treatment tray by its placement over the person's teeth; and a dental treatment composition placed onto the barrier layer prior to its placement over the patient's teeth. 2. A tray-shaped dental treatment device as recited in claim 1, wherein said support skeleton comprises an exoskeleton having a tray-like configuration configured to receive said moisture-resistant barrier layer. 3. A tray-shaped dental treatment device as recited in claim 2, wherein said exoskeleton includes a handle. 4. A tray-shaped dental treatment device as recited in claim 1, wherein said dental treatment composition comprises at least one of a sticky viscous gel, a less viscous gel, a highly viscous putty, or a substantially solid composition. 5. A tray-shaped dental treatment device as recited in claim 4, wherein the dental treatment composition includes at least one tissue adhesion agent. 6. A tray-shaped dental treatment device as recited in claim 5, wherein said dental treatment composition further includes at least one active agent. 7. A tray-shaped dental treatment device as recited in claim 6, said active agent comprising at least one of a dental bleaching agent, a desensitizing agent, a remineralizing agent, an antimicrobial agent, an antiplaque agent, an anti-tartar agent, or another medicament. 8. A tray-shaped dental treatment device as recited in claim 5, said tissue adhesion agent comprising polyvinyl pyrrolidone. 9. A tray-shaped dental treatment device as recited in claim 5, said tissue adhesion agent comprising at least one of carboxypolymethylene, polyethylene oxide, polyacrylic acid, copolymer of polyacrylic acid, polyacrylate, polyacrylamide, copolymer of polyacrylic acid and polyacrylamide, PVP-vinyl acetate copolymer, carboxymethylcellulose, carboxypropylcellulose, polysaccharide gum, and protein. 10. A tray-shaped dental treatment device as recited in claim 5, said tissue adhesion agent having a concentration in a range of about 10% to about 90% by weight of said treatment composition. 11. A tray-shaped dental treatment device as recited in claim 5, said tissue adhesion agent having a concentration in a range of about 20% to about 80% by weight of said treatment composition. 12. A tray-shaped dental treatment device as recited in claim 5, said tissue adhesion agent having a concentration in a range of about 40% to about 75% by weight of said treatment composition. 13. A tray-shaped dental treatment device as recited in claim 5, wherein the treatment composition comprises a substantially solid adhesive composition and at least one of a sticky viscous gel, a less viscous gel, or a highly viscous putty adjacent to at least one of said adhesive composition or said barrier layer. 14. A tray-shaped dental treatment device as recited in claim 1, wherein said device is contained within a sealed package prior to use. 15. A dental treatment system for use in applying a treatment composition to a person's teeth, comprising: a moisture-resistant barrier layer having a front side wall and a bottom wall, and that is adapted to be worn over at least a portion of a person's upper or lower dental arch without requiring customization prior to wearing, the barrier layer comprising a thin-walled, flexible membrane material that is adapted to at least partially conform to the person's teeth when placed over a patient's teeth to apply the treatment composition; said barrier layer comprising one or more anatomical features that facilitate the ability of the barrier to conform to the patient's teeth when worn for treatment; a support skeleton positioned adjacent to the barrier layer prior to placement over the patient's teeth so as to maintain the thin-walled flexible membrane material in a tray-like configuration to facilitate placement of the barrier layer when forming the treatment tray by its placement over the person's teeth; and a substantially solid adhesive composition that has increased adhesiveness to teeth when moistened with saliva or water, said adhesive composition including; at least one active agent; and at least one tissue adhesion agent that contributes or provides increased adhesiveness to oral tissue when moistened with saliva; and at least one of a sticky viscous gel, a less viscous gel, or a highly viscous putty adjacent to at least one of said barrier layer or said adhesive composition. 16. A tray-shaped dental treatment device as recited in claims 1 or 15, wherein said one or more anatomical features comprise a plurality of cuts positioned so as to help said bottom wall better conform to abrupt changes in the diameter of a person'teeth where the bicuspids and canines meet, and wherein each of said cuts comprises a notch. 17. A tray-shaped dental treatment device as recited in claims 1 or 15, wherein said one or more anatomical features comprises a notch in said bottom wall so as to help said tray-shaped dental treatment device to more easily spread open or compress in the area of a person's incisors. 18. A tray-shaped dental treatment device as recited in claims 1 or 15, wherein said one or more anatomical features comprises at least one V-shaped or U-shaped indentation in said bottom wall configured to be inserted into the depression typically found along the top surfaces of a person's molars. 19.
