Making a model of your teeth is a short process that can be completed in less than an hour. Using dental alginate and plaster, you can create a perfect model of your teeth and gums, either for viewing as is, or as a model to use in order to create teeth prosthetics good enough for theatrical use.

Things you need
- Dental grade alginate
- Cold water
- Plastic cups
- Drill with wire whisk
- Styrofoam cups
- Plastic spoon
- Hobby knife
Mix the alginate with the water according to the manufacturer's instructions using the drill with whisk attachment in a plastic cup. Dental alginate is a rubbery material that can capture fine details and is safe to use in the mouth to create a mold. Add the powder to the liquid to cut down on bubbles, which can create holes in the mold.
Pour the mixed alginate into the dental tray and then press the tray into your jaw covering your upper teeth. The dental tray is simply a flat tray that's large enough to fit into your mouth with the alginate covering the entire row of teeth. The bottom of a Styrofoam cup is a good material to use for a tray. Rip the edges off the bottom and then place the alginate onto the flat surface.
Allow the alginate to firm up for 2 to 3 minutes and then remove it from your mouth. Remove any excess alginate from the tray, and then remove the tray from the firmly set alginate.
Mix the plaster according to the manufacturer's directions in a plastic cup using a plastic spoon, adding powder to liquid.
Place the alginate mold into a Styrofoam cup and then pour the plaster mixture into the cup completely covering the mold. Tap the sides of the cup to force any bubbles in the mixture to the top. Allow 40 minutes for the plaster to set.
Remove the Styrofoam from the plaster piece as well as the alginate to reveal the perfectly modeled row of teeth. Repeat the entire process for the lower row of teeth to create a complete set.
Remove any excess plaster from the casting using the knife and file to complete the model.
