- 1). Rinse an empty white dish-washing liquid bottle, and make sure all the soap is out.
- 2). Measure the distance between the two teeth where you want your fangs to go.
- 3). Draw a rectangle on the curved side of the bottle that is 1/4 inch wide and the length that you measured in Step 2.
- 4). Draw two fangs on the front of the rectangle about 1.5 inches apart. They can be as long as you want, but 1/2 to 1 inch is typical.
- 5). Cut out the fangs with scissors or a box cutter.
- 6). File any sharp edges or rough spots with a nail file, and wash the fangs. Place them in your mouth with the curve in the roof to test for a good fit. Trim as needed.
