What is claimed is:

1. A method of preparing an anatomically disproportionate artificial tooth apparatus for use in a human mouth with human teeth, comprising the steps of:

(a) molding an anatomically disproportionate artificial tooth having an interior cavity;
(b) thereafter inserting an impression compound into said interior cavity;
(c) thereafter coating said interior cavity with said impression compound forming a liner whereby an anatomically disproportionate artificial tooth assembly is formed;
(d) thereafter positioning said anatomically disproportionate artificial tooth assembly over at least one of said human teeth in said mouth;
(e) thereafter waiting 3 to 10 minutes with said anatomically disproportionate artificial tooth assembly in position whereby said impression compound sets; and
(f) thereafter removing said anatomically disproportionate artificial tooth assembly from said mouth.

2. The method of claim 1, further comprising the steps of:

(a) applying denture adhesive to said liner after removal from said mouth;
(b) thereafter positioning said anatomically disproportionate artificial tooth assembly over said human teeth.

3. An anatomically disproportionate artificial tooth apparatus produced in accordance with claim 1.

4. The method of claim 1, wherein said anatomically disproportionate artificial tooth assembly comprises a material selected from the group consisting of acrylic plastic, ABS (acrylonitrile-butadiene-styrene) plastic, thermoforming plastic, polyethylene, polypropylene, porcelain, and nylon.

5. The method of claim 1, wherein said anatomically disproportionate artificial tooth assembly consists essentially of a fang-shaped artificial tooth.

6. The method of claim 1 wherein the anatomically disproportionate artificial tooth assembly further comprises an artificial gum.

7. The method of claim 6, wherein the method of preparing the artificial gum comprises the steps of:

(a) mixing a gum resin and a gum solvent to form a gum gel; and
(b) embedding said anatomically disproportionate artificial teeth in said gum gel.

8. An artificial cosmetic tooth assembly for use in a mouth over existing human teeth, comprising:

at least one anatomically disproportionate artificial tooth having an interior cavity; and
a liner, prepared by utilizing an impression compound to form a liner, placing said liner in said interior cavity, placing said anatomically disproportionate artificial tooth with said liner over said existing human teeth, waiting for said liner to set whereby a custom impression of said existing human teeth is formed, and removing said anatomically disproportionate artificial teeth from said mouth.

9. The artificial cosmetic tooth assembly of claim 8, wherein:

said anatomically disproportionate artificial teeth being embedded in an artificial gum assembly; and
said gum assembly being prepared by:
(a) mixing a resin and a solvent to form a non-tacky gum gel;
(b) positioning said anatomically disproportionate teeth in standard mold;
(c) placing said gum gel into said standard mold;
(d) waiting for said gum gel to set, whereby a flexible elastomeric artificial gum is formed, and;
(e) removing said gum assembly from said standard mold.

10. The artificial cosmetic tooth assembly of claim 8 wherein said liner comprises a partial plate.

11. The artificial cosmetic tooth assembly of claim 8 wherein said at least one anatomically disproportionate artificial tooth comprises at least one incisor.

12. The artificial cosmetic tooth assembly of claim 8 wherein said at least one anatomically disproportionate artificial tooth comprises a set of upper teeth.

13. The artificial cosmetic tooth assembly of claim 12 wherein said set of upper teeth are equal in size and shape.

14. An artificial cosmetic tooth assembly for placement over human teeth, comprising:

at least one anatomically disproportionate artificial tooth having an interior cavity; and
a liner, prepared by impressing an impression compound between the interior cavity of said artificial tooth and said human teeth, whereby a custom fit is provided.

15. The assembly of claim 14, wherein said anatomically disproportionate artificial tooth assembly further comprises a material selected from the group consisting of acrylic plastic, ABS (acrylonitrile-butadiene-styrene) plastic, nylon, and porcelain.

16. The apparatus of claim 14, wherein said impression compound comprises a mixture of a resin and a solvent.

17. The apparatus of claim 16, wherein:

said resin comprises a thermoplastic granular lower-alkyl methacrylate copolymer;
said solvent comprises from about 10 to 50 volume percent alcohol;
said solvent further comprises an oil extender, whereby the set time of said impression compound is extended; and said solvent further being present from about 5 to about 12 cc. per 10 grams of said resin.

18. The apparatus of claim 14, wherein said anatomically disproportionate artificial tooth assembly consists essentially of a substantially fang-shaped artificial tooth.

19. The apparatus of claim 14, wherein said anatomically disproportionate artificial tooth assembly further comprises an artificial gum.

20. The apparatus of claim 19, wherein:

said artificial gum is prepared by the steps of:
(a) placing anatomically disproportionate artificial teeth in a mold;
(b) mixing a gum resin and a gum solvent to form a gum gel;
(c) placing said gum gel in said mold, and;
(d) removing said artificial gum from said mold after 20 to 30 minutes whereby said gum gel has cured.

21. The artificial cosmetic tooth assembly of claim 14 wherein said liner comprises a partial plate.
