1 Choose a photo

The first step is to choose a photo that has teeth that you want to fix. Ideally, the photo should be high-resolution, well-lit, and show the teeth clearly. You can use your own photos or download free stock photos from sites like Unsplash or Pexels. Open the photo in Photoshop and make a duplicate layer by pressing Ctrl+J (Windows) or Command+J (Mac). You will work on this layer and keep the original as a backup.

2 Zoom in and select the pen tool

The next step is to zoom in on the teeth area and select the pen tool from the toolbar. The pen tool lets you draw smooth curves and straight lines that form a path. A path is a vector shape that can be modified, filled, or stroked. To use the pen tool, click on the edge of a tooth to create an anchor point. Then, drag the cursor to create a direction line that defines the curve of the path. Click on another point on the edge of the same tooth and adjust the direction line as needed. Repeat this process until you have traced the outline of the tooth. To close the path, click on the first anchor point or press Ctrl+Enter (Windows) or Command+Return (Mac).

1. Preparation: Open your image in Photoshop. Duplicate the background layer (Right-click the background layer and choose "Duplicate Layer"). This creates a non-destructive editing base. 2. Zoom In and Select the Pen Tool: Use the Zoom tool (magnifying glass icon) or keyboard shortcut (Ctrl+Plus or Cmd+Plus) to zoom in for precise selection. Locate the Pen Tool (pen nib icon) in the toolbox. You can also press P on your keyboard.

3 Create a selection from the path

The third step is to create a selection from the path that you have drawn. A selection is a marquee that isolates a part of the image that you want to edit. To create a selection from the path, go to the Paths panel and right-click on the path thumbnail. Choose Make Selection from the menu and set the Feather Radius to 0.5 pixels. This will create a soft edge for the selection. You can also press Ctrl+Enter (Windows) or Command+Return (Mac) to create a selection from the path.

1. Create a Path Around the Tooth: Click on a point where you want to start tracing the outline of the tooth. This creates the first anchor point. As you move your cursor around the tooth, click to create additional anchor points, following its curves and edges. Hold Alt (Option on Mac) while clicking to create a corner point (sharp angle). For smooth curves, click and drag slightly away from the tooth edge to create direction handles (little lines extending from the anchor point). Adjust these handles to control the curve's shape. 2. Close the Path: Once you've traced the entire tooth outline, click back on the first anchor point to close the path. A closed path is indicated by a solid line connecting all the anchor points.

4 Modify the color and brightness of the tooth

The fourth step is to modify the color and brightness of the tooth that you have selected. You can use various adjustment layers and filters to change the appearance of the tooth. For example, you can use a Curves adjustment layer to increase the contrast and brightness of the tooth. To apply the adjustment only to the selected tooth, click on the clipping mask icon at the bottom of the Layers panel. This will limit the effect of the adjustment layer to the layer below it. You can also use a Hue/Saturation adjustment layer to reduce the yellow or red tones in the tooth. To fine-tune the color, click on the Master dropdown menu and choose Yellows or Reds. Then, drag the Saturation slider to the left to desaturate the color.

Modify the Tooth: You have a selection around the tooth, you can modify its appearance. Here are some options: Color: Go to "Image" > "Adjustments" and choose an option like "Hue/Saturation" or "Selective Color" to adjust the tooth's color. Brightness: Use "Levels" or "Curves" adjustments (Image > Adjustments) to brighten or darken the tooth. Whitening: Consider using tools like "Dodge & Burn" or selective adjustments with a brush to create a whitening effect.

5 Repeat for the other teeth

The fifth step is to repeat the previous steps for the other teeth that you want to fix. You can use the same path that you have created for the first tooth and modify it for the other teeth. To do this, select the path selection tool from the toolbar. The path selection tool lets you move, resize, rotate, or transform a path. To use the path selection tool, click on the path that you have drawn and drag it to another tooth. You can also use the handles and anchor points to adjust the shape of the path. Then, create a selection from the path and apply the same adjustments as before.

6 Align and straighten the teeth

The final step is to align and straighten the teeth if they are crooked or uneven. You can use the free transform tool to rotate, skew, or distort a selection. To use the free transform tool, press Ctrl+T (Windows) or Command+T (Mac) and drag the handles or corners of the selection. You can also use the warp mode to bend or twist a selection. To use the warp mode, right-click on the selection and choose Warp from the menu. Then, drag the grid points or lines to warp the selection. Press Enter to apply the transformation.
