Vampires are well-known mythical creatures that bite people's necks because they survive on human blood. These creepy creatures are fascinating to most people, and a vampire costume is always one of the most picked for Halloween and other costume parties. The vampire fangs you can purchase at party stores usually look fake and are uncomfortable. You can make your own realistic fangs at home that will look much more authentic with little trouble.
Make a mould of your teeth from aluminium foil. Fold a piece of 5 inch long foil into a "U" shape about 1 inch thick. Press this foil into your upper teeth to create a foil cast mould of your teeth.
Fill the tooth tray 2/3rds of the way full with the alginate material. Place the mould back in your mouth and bite down. Take care not to bite too hard or your teeth will reach the bottom of the tray, which will ruin the mould. Hang your head down over a sink so that you do not swallow the unpleasant tasting alginate.
Allow the alginate to set for about 5 to 10 minutes. It will turn rubbery in your mouth and you should be able to feel it. Remove the mould from your mouth. Rinse your mouth with water or mouthwash to clean it.
Rinse the mould with water and dry with a paper towel. Fill the mould with plaster and allow it to sit for 24 hours. Remove the teeth cast from the alginate and foil.
Roll two balls of clay about the size of a pencil eraser or the tip of your pinky nail. Cover the incisor teeth on the mould with petroleum jelly. Fit the clay balls over your incisor teeth on the plaster mould.
Mold the balls so that the clay reaches half way up the back of the tooth and all the way up the front of the tooth. Shape the clay into vampire fangs. Do not make the fangs so large that they will pinch your lips when you wear them.
Cook the mould and the clay fangs in the oven according to the package directions. These will change, but it usually takes less than one hour to bake such a small amount of clay. Remove the fangs from the mould and discard the mould. You will only use the plaster fangs.
Smooth any rough fang edges with sandpaper. Paint the fangs as desired with acrylic paint. Use denture adhesive to hold the fangs over your teeth.
