Whether you're getting ready for Halloween, going to a themed event, or creating a costume for a theatrical production, fake teeth can make your character more authentic. If you have a pair of fake teeth -- these can be found at any costume or theatrical make-up shop -- you can colour them with safe, non-toxic theatrical tooth paint that is safe even for dentures and natural teeth. Paint some of the teeth black to make it look as if you're missing teeth. Use gold paint to create gold crowns. Or paint the fake teeth in a yellow or brown colour to make it look as if they are decayed.
Shake the bottle of theatrical tooth paint thoroughly. You can find tooth paint at costume stores or online by searching for "tooth paint."
Place your fake teeth on a piece of paper towel. Remove the top of the tooth paint bottle. You'll notice a brush is attached to the top like a nail polish bottle.
Scrape the brush against the inside of the bottle's lid, lightly, to remove excess paint from the brush.
Brush the colour onto the tooth or teeth that you'd like to decorate. Cover the tooth thoroughly with the paint so that it completely changes colour.
Allow the teeth to sit until the paint is dry to the touch -- about 5 minutes -- before adding a second coat, if necessary.
Scrape the teeth with your fingernail or a toothpick to remove the paint when finished.
