A method for producing a tooth, the method comprising:
- isolating or obtaining mesenchymal cells from an amnion and preparing a first cell mass consisting essentially of the mesenchymal cells;
- isolating or obtaining epithelial cells from a tooth germ and preparing a second cell mass consisting essentially of the epithelial cells;
- positioning said first and second cell masses in a support carrier capable of promoting tooth formation, wherein the first and second cell masses are not mixed but placed in close contact with each other within the support carrier;
- and
- culturing the first and second cell masses in the support carrier for an amount of time sufficient to produce a tooth.
