* Black acrylic paint
* Clear nail polish
* Small paintbrush
1. Paint your teeth with the black acrylic paint. Allow the paint to dry completely.
2. Apply a layer of the clear nail polish to your teeth. This will help to seal in the paint.
3. Let the nail polish dry and you are done!
* If you want the black teeth to look more realistic, you can add a little bit of brown acrylic paint to the black paint.
* You can also add some fake blood or food coloring to the teeth, to make them look even more creepy.
* Black teeth are a great way to add a little bit of spooky fun to your Halloween costume!
