Do you want to dress like a vampire for Halloween or for a costume party but don't want to wear plastic fangs? You can make a pair of vampire fangs using basic dental supplies. These fangs will look very realistic and can be made to fit your mouth--because you will make a mould of your teeth and form the fangs. The needed items can be found at a dentist's office or medical supply shop.
Cut off the bottom of a paper coffee cup off with scissors. The bottom piece should be 1½ inches tall.
Cut out a crescent moon shape from the piece of the cup. The piece of cup should be able to fit into your mouth like an impression tray you would use at the dentist. Angle the vertical sides of the cup so it fits into your mouth more comfortably.
Mix 1½ tbsps. of alginate powder and 1½ tbsps. of water in a clean bowl. Tap the bowl on the table to release any air bubbles that are trapped in the paste as you mix it.
Pour the alginate paste into the impression tray and spread it out evenly.
Insert the impression tray into your mouth and bite down until the alginate reaches past your gum line. Your teeth shouldn't touch the bottom of the cup.
Leave the alginate in your mouth for three minutes, then gently pull out the tray. Work slowly and be careful not to tear the alginate when removing it from your teeth.
Mix 1/3 cup of water and 1/3 cup of plaster in a bowl. Follow the directions on the plaster package for the specific mixing time required.
Place the impression tray inside another paper coffee cup. The tray should sit on the bottom of the cup like stacked cups would.
Pour the plaster into the coffee cup so the alginate is completely covered and let it set until the plaster is solid. Plaster setting takes at least an hour.
Tear the coffee cup and peel it away from the plaster filling and the impression tray.
Grasp the impression tray with one hand and the plaster in the other and slowly ease them apart. Apply petroleum jelly along the teeth and gum line of the plaster cast. Set aside the plaster cast of your teeth.
Follow the directions on the acrylic and monomer products for the correct amounts to make a very tiny batch of acrylic. You only need enough to form one fang. Mix the acrylic liquid and powder with monomer in a well-ventilated area as they monomer has a strong smell. As you mix the materials together the acrylic will start to become more solid.
Pick up the acrylic and wad it into an oblong shape, a little longer than you want the fang to be.
Push the acrylic onto one of the canines of your plaster cast. The canine is the third tooth from the centre of your mouth in either direction. It has a small point like a dog's tooth. Make sure the acrylic is touching the gum line and is securely holding onto the tooth and surrounding area and that it is roughly shaped like a fang.
Let the acrylic harden. Then very carefully pull it off of the plaster.
Smooth down the edges of the acrylic with a small dremel tool. Run the dremel's head along the fang until it looks natural. Put the fang on your canine occasionally to see where you need to make adjustments with the dremel.
Make more acrylic and shape another fang for your other canine.
The alginate has a slightly unpleasant taste and should not be swallowed when you put the impression tray in your mouth.
