Complete Guide on How to Whiten Teeth in Photoshop

Teeth whitening can improve your subject’s appearance, which could lead to more employment for you. We'll take you to step by step through the procedure in this Photoshop tutorial.

You've probably heard of Photoshop, whether you're a professional photographer or not. Photoshop is a photo-editing tool that many people use. 

Photoshop allows users to modify photographs in a variety of ways, so it's no wonder that teeth whitening has made its way into the program.

After all, it's a well-known fact that the majority of people desire white teeth. While teeth whitening at the dentist is costly and can harm your teeth, learning how to whiten teeth in Photoshop is a low-cost solution that produces effects in minutes.

Follow these instructions to know more about how to whiten teeth in Photoshop.

How To Whiten Teeth in Photoshop?

Step 1: Open Adobe Photoshop and Select Your Image

Select Open from the File menu and select your image.

Step 2: Prepare Your Picture File for Teeth Whitening

Take a look at the image you've chosen. If the shot only has one subject, the whitening process will only need to be done once. If there are more subjects, you'll have to repeat the process. Perform each of these steps for each subject separately. You can change the teeth of one subject without impacting the teeth of the other in the original photograph.

By using CTRL (for Windows) or CMD (for Mac) on your keyboard and the + sign, you can zoom in on the first person's teeth until you can see the entire smile.

Step 3: Using the Lasso Tool to Draw a Selection around the Teeth

In the Toolbar panel, select the Lasso Tool. Make a selection all the way around the teeth. If you're using a mouse, your selection might not be as accurate as you'd want. But don't worry, you'll have the opportunity to change it later.

Step 4:  Add a Hue/Saturation Adjustment Layer

Click the New Fill or Adjustment Layer button in the Layers panel. A drop-down menu of Adjustment Layer options will appear. Select Hue/Saturation from the drop-down menu.

In the Layers panel, you’ll see a new Hue/Saturation layer above your Background layer. If you only need to whiten one set of teeth, you can skip this layer. Rename the layer if you have many sets of teeth to whiten. Renaming the layer will make it easier to figure out which set of teeth it belongs to.

Step 5: Change the Layer Options to Yellows

We'll concentrate on minimizing the yellowness of the teeth in question when it comes to tooth whitening. Click where it reads Master in the Hue/Saturation layer's Properties Panel to bring up a drop-down option.

Choose Yellows from the drop-down menu. Changes to this adjustment layer will now only affect the yellows in the selection.

Step 6: Reduce the Yellow Saturation Level

Drag the Saturation slider to the left. If you go too far to the left, your image modifications will appear phony. Concentrate on gradually lightening the color of your teeth.

Step 7: Double-check Your Work

Zoom out as you make changes to see how the image looks from a distance. Click the eye icon next to the Hue/Saturation adjustment layer to turn your yellow adjustments on and off.

If your changes appear to be too evident, go back in and make any necessary changes.

Step 8: Whiten the Teeth

When you're pleased with the yellow adjustments, go to the Properties box and choose Yellow. Choose Master. Your changes will now be applied to all colors in the selection.

Drag the Lightness slider to the right to brighten the teeth. To double-check your work, you can zoom in and out or switch the adjustment layer on and off, just as before.

Step 9: Clean up the Selection Area

If you didn't choose all of the teeth cleanly, or if you mistakenly selected the lips or gums, now is the moment to fine-tune your selection.

In the Layers panel, look at the Layer Mask thumbnail for your Hue/Saturation layer. The foreground color of the document will be used to fill in the thumbnail (in this case black). White (the document's background color) will be visible in the sections we've picked and altered.

Here's how to make rapid changes to your selection:

  • In the Tool panel, choose the Brush Tool.

  • Select the foreground color (black) as your paint color to paint out parts that shouldn't be whitened (lips, gums, etc.). To eliminate certain spots from the selection, paint them.

  • Select the backdrop color (white) as your paint color to fill in sections you missed in your initial selection (parts of the teeth you may have overlooked). To include certain regions in the selection, paint them.

If your photograph contains more persons, return to step 3 and repeat the process for each additional person. Remember that the teeth should never be the focal point of the face.
