Things You'll Need
Alginate molding powder (available at many pharmacies or dentists' offices)
Aluminum foil
Craft plaster
Paper towels
Small paintbrush
White or cream-colored non-toxic oven-bake polymer clay (available at most craft stores)
Cookie sheet
Oven
Whether you're planning on dressing as a werewolf for Halloween or a costume party, you don't need to spend a lot of money on store-bought werewolf fangs. Instead, you can use some easy-to-acquire household items to make your own werewolf fangs at home. First, you must make a cast of your teeth. Then, you can use polymer clay to mold your own custom-fitting werewolf fangs.
Making a Cast of Your Teeth
Step 1
Bend a sheet of aluminum foil into a "U" shape using your hands. The "U" should be about the size of your upper row of teeth. Use scissors to trim the edges of the "U" so that it will fit in your mouth.

Step 2
Test to make sure that the foil "U" fits in your mouth with enough excess foil to mold around your top row of teeth. The foil mouth piece should look like a sports mouth guard.
Step 3
Flatten the sides of the foil "U" to create a shape like a dental mouth tray.
Step 4
Mix one tablespoon of alginate powder with one tablespoon of water, and fill the foil tray about 2/3 full with this mixture.
Step 5
Press the foil tray with the alginate powder around your top row of teeth. Bite down gently. Biting too hard will split the alginate mold at the bottom.
Step 6
Keep the mold in your mouth until the alginate begins to harden. It will feel firmer and more rubbery as it sets.
Step 7
Remove the mold from your mouth after several minutes, and place it on a hard surface. Spit out any alginate molding left in your mouth.
Step 8
Pat dry the alginate mold with a paper towel to soak up any excess water or saliva.
Step 9
Mix about a tablespoon of craft plaster with a tablespoon of water. Follow the directions on the plaster package about the exact proportions of plaster to water.
Step 10
Brush the plaster onto the inside of the alginate mold, using the paintbrush. Make sure to cover all cracks and crannies. Apply plaster generously.
Step 11
Pour the remaining plaster into the alginate mold until it is full. Gently tap the mold on a hard surface such as a table or counter to remove any air bubbles within the plaster.
Step 12
Allow the plaster mold to sit for several hours until it has dried completely. Once the plaster has dried, peel back the alginate to reveal an exact replica of your top teeth in plaster.
Making Werewolf Fangs
Step 1
Make several pencil eraser-sized balls of polymer clay with your hands.
Step 2
Place one clay ball on each of the front 6 teeth of your plaster teeth mold, and mold the clay around the teeth. Make sure to mash the clay pieces together to form one solid mouth piece.
Step 3
Take two more balls of clay, and focus your attention on the two canine teeth. Using the extra clay, form pointed fangs on these canine teeth. Don't make them too long; you need to be able to bite down while wearing them.
Step 4
Bake the polymer clay teeth. Place the entire mold -- plaster tooth mold and polymer clay -- on a cookie sheet, and bake it in the oven at the temperature indicated on the polymer clay packaging. Check the teeth every few minutes to make sure the polymer clay is not burning.
Step 5
Allow the hardened polymer clay teeth to cool completely. Then, remove the polymer clay from the plaster molding. You might have to wriggle it off, since it will stick firmly during baking. Now you have your custom-made werewolf fangs!
Tip
As you are molding the alginate around your teeth, lean forward over the sink to prevent any alginate molding from running down your throat.
Do not eat or bite down too hard while wearing your homemade fangs.
The fangs should stay on your teeth without difficulty. However, if they tend to slide, you can use denture adhesive to keep them in place.
