Turn Teeth into Sharp Fangs in Photoshop

Turn Teeth Into Sharp Fangs in Photoshop

Turning normal teeth into convincingly sharp, monster-style fangs starts with a rough sketch, then moves through the Pen tool, painted depth and highlights, and a pass of Liquify for teeth that don’t need as much individual attention. This tutorial builds one detailed fang from scratch before showing a faster Liquify-based method for the rest.

Sketching the Fang Shapes Before Building Them

A rough sketch, made with a sampled tooth color on a new layer, works out the shape of each fang before any precise selection work begins.

1. Sample the Existing Tooth Color

   Create a new layer, select the Brush tool, and hold Alt/Option to sample the color of the existing white teeth.

2. Sketch Rough Fang Shapes

   Loosely sketch out where and how long each fang should be, adjusting length and curve with the Eraser tool as needed.

Why Sketching First Saves Time With the Pen Tool

Jumping straight into a precise Pen tool selection without a clear idea of the final shape tends to waste time on edits and second-guessing. A rough sketch settles the overall shape and length first, so the more careful Pen tool work that follows has a clear target to trace rather than being figured out on the fly.

Tracing an Accurate Selection With the Pen Tool

Tracing directly over the sketch with the Pen tool turns a rough idea into a precise, editable selection ready for painting.

3. Trace the Sketch With the Pen Tool

   Press P for the Pen tool and trace around the sketched fang shape, using as few points as possible for smoother curves.

4. Name and Save the Path

   Name the finished path, such as Tooth One, in the Paths panel.

5. Turn the Path Into a Selection

   Hold Cmd/Ctrl and click the path’s thumbnail to load it as a selection on a new layer.

Painting Base Colors and Depth Into a Tooth

Sampling and painting darker and lighter tones from the existing teeth gives the new fang shape a sense of real depth rather than looking like a flat, painted-on shape.

6. Hide the Selection for a Clearer View

   Press Cmd/Ctrl+H to hide the selection’s marching ants while painting.

7. Paint Darker Tones Toward the Edges

   Sample and paint darker colors from the existing tooth, keeping them mainly toward the edges rather than the center.

8. Paint Lighter Tones Toward the Center

   Sample and paint lighter tones toward the center of the tooth, since darker edges and a lighter center are what suggest real depth.

Copying and Warping a Highlight to Follow the Tooth’s Curve

A cloned highlight, set to Lighten and warped to match the tooth’s curvature, gives the fang the same kind of shine visible on the surrounding real teeth.

9. Clone an Existing Highlight

   Press S for the Clone Stamp tool, hold Alt/Option to sample an existing highlight, and paint it onto a new layer over the new tooth.

10. Set the Highlight Layer to Lighten

    Change the highlight layer’s blend mode from Normal to Lighten so it only brightens rather than darkens.

11. Warp the Highlight to Follow the Tooth’s Shape

    Press Cmd/Ctrl+T, right-click and choose Warp, and reshape the highlight so it follows the curvature of the tooth.

Blurring and Adjusting the Tooth for Realism

A very small Gaussian Blur softens a new tooth’s edges to match the surrounding image resolution, and the underlying pen path can still be adjusted at any point afterward.

12. Apply a Small Gaussian Blur

    Go to Filter > Blur > Gaussian Blur and apply a very small amount to help the new tooth blend with the rest of the mouth.

13. Group the Tooth’s Layers Together

    Select the tooth’s layers and group them together, naming the group after that specific tooth.

14. Revisit and Adjust the Pen Path if Needed

    Return to the saved path with the Pen tool at any time, hold Cmd/Ctrl to move individual points, and reload it as a selection to fix the painted layers to match.

Why Paths Are Easier to Adjust Than a Finished Selection

Since the tooth’s shape is stored as an editable path rather than a one-time selection, its curve can be refined at any point without starting the painting work over. Reopening the path, moving a point, and reloading the updated selection is far faster than trying to manually repaint an entire tooth from scratch.

Repeating and Extending the Technique to Additional Teeth

The same combination of sketch, path, painted color, and warped highlight repeats for each additional tooth, with highlights sometimes extended further down using the Clone Stamp tool.

15. Repeat the Full Process for Each Tooth

    Sketch, trace with the Pen tool, paint base colors, and add a warped highlight for each additional tooth being sharpened.

16. Extend a Highlight Further Down a Tooth

    Clone the highlight onto a new layer set to Lighten and warp it with Cmd/Ctrl+T to extend it further down a tooth, masking away any part that shouldn’t be visible.

Adding Imperfections for Realism

Small painted chips and dings, softened with a touch of blur, keep a full set of newly created fangs from looking unnaturally flawless.

17. Select Small Areas With the Lasso Tool

    Use the Lasso tool, holding Shift to add multiple small selections, to mark a few spots for chips or nicks on the teeth.

18. Paint Black to Create Chips and Dings

    Paint black within those selections on a new layer above the teeth to simulate small imperfections.

19. Soften the Imperfections With Gaussian Blur

    Go to Filter > Blur > Gaussian Blur and apply a small amount to the painted imperfections so they look worn rather than too sharply defined.

Sharpening Teeth Quickly With the Liquify Tool

The Liquify filter’s Forward Warp tool offers a much faster, if less precise, alternative for reshaping teeth that don’t need the same level of individual detail.

20. Create a Stamp Visible Layer

    Press Shift+Option/Alt+Cmd/Ctrl+E to merge everything visible onto a new layer.

21. Select the Area and Open Liquify

    Make a selection around the teeth to edit, then go to Filter > Liquify.

22. Pull Points Up Into Shape With Forward Warp

    Use the Forward Warp tool, with a larger brush for overall shape and a smaller brush for sharp points, to pull each tooth into a pointed fang shape.

23. Apply and Undo Freely to Compare Results

    Apply the Liquify transformation and undo it to compare before-and-after versions until the shape looks right. The same Liquify pass also works for subtle final refinements to the Pen tool teeth on top, since their edges are already clean.

Why the Liquify Method Trades Control for Speed

Building a tooth from a sketch, a Pen tool path, painted color, and a warped highlight gives complete control over every detail, but takes real time to do well. The Liquify method reshapes existing teeth directly and much faster, at the cost of the fine-grained control that painting a tooth from scratch provides, which makes it a reasonable trade-off for teeth that don’t need as much individual attention.

Why This Approach Works

Sketching a rough shape before ever touching the Pen tool is what keeps the more precise selection work focused and efficient rather than being figured out step by step. Storing each tooth’s shape as an editable path is what makes it possible to revise a curve after the fact without repainting the entire tooth from scratch. Adding small chips and imperfections at the end is what keeps a full set of freshly created fangs from looking unnaturally perfect, which is often the detail that separates a convincing result from an obviously digital one.

Final Thoughts

Between the detailed Pen tool method for the top teeth and the much faster Liquify approach for the bottom, both techniques produced convincing results in their own way. Either method, or a combination of both, works on any portrait that calls for a set of sharp, monster-style teeth.
