Step-By-Step Instructions:
1. In Photoshop, open a photo of a person whose teeth are showing.
2. Select the Clone Stamp tool and zoom in on the two front teeth.
3. Hold down the ALT key and click over one of the two front teeth to select it.
4. Now let go of the ALT key and paint the copied clone stamp texture just below the teeth to extend the teeth length.
5. Be sure to paint the same shape on the bottom of the teeth.
6. Select the smudge tool and choose an appropriate size brush.
7. Smudge the shading of the front teeth so that they look real.
8. Select the Burn tool.
9. Choose a small brush size. Then use the burn tool just below the teeth to give some shadow on the lips so that it looks like the the teeth are overlapping the lips and casting a shadow.
10. You're done! The person in the photo should now have the appearance of buck teeth.
