Step-by-Step Guide: How to Whiten Teeth in Photoshop

◾ Step 1: Select the Teeth Precisely

1. Duplicate your image layer (Ctrl + J / Cmd + J).

2. Use the Lasso Tool or Quick Selection Tool to select the teeth.

3. Apply Feather (5–10 px) for smoother edges.

4. Refine your selection with Select and Mask if needed.

◾ Step 2: Reduce Yellow Tones with Hue/Saturation

1. Click New Adjustment Layer > Hue/Saturation.

2. In the dropdown, choose Yellows.

3. Reduce Saturation until the yellow fades.

4. Slightly increase Lightness to brighten the area.

◾ Step 3: Brighten with Curves Adjustment

1. Add a Curves Adjustment Layer.

2. Create a soft “S” curve to brighten highlights.

3. Use a layer mask and a low-opacity black brush to erase over-bright areas.

◾ Step 4: Final Enhancements with a Soft Brush

1. Choose the Brush Tool, set it to White, 20–30% opacity.

2. Paint gently over the teeth to enhance the glow.

3. Lower the layer’s opacity for a more natural look.

4. Use the Blur Tool (low strength) to soften any hard edges if needed.

Advanced Tips for Natural Results

• Preserve texture: Don’t push brightness so far that enamel texture disappears.

• Use blending modes: Try "Soft Light" or "Overlay" for gentle enhancement.

• Consider skin tone: Overly bright teeth can look unnatural next to warm complexions.

Common Mistakes to Avoid
