Whitening Teeth

This really should be called "Removing Yellowing, then Whitening Teeth" because almost everyone has some yellowing, so we remove that first before we move on to the whitening process. This is a simple technique, but the results have a big impact on the overall look of the portrait, which is why I do this to every portrait where the subject is smiling.

Step One

Open the photo you need to retouch. Press L to switch to the Lasso tool, and carefully draw a selection around the teeth, being careful not to select any of the gums or lips. Note: Press the Z key to switch to the Zoom tool and zoom in if needed.

Step Two

Go under the Select menu and choose Feather. When the Feather Selection dialog appears, enter 1 pixel and click OK to smooth the edges of your selection. That way, you won't see a hard edge along the area you selected after you've whitened the teeth.

Step Three

Go under the Image menu, under Adjustments, and choose Hue/Saturation. When the dialog appears, choose Yellows from the Edit popup menu at the top. Then, drag the Saturation slider to the left to remove the yellowing from the teeth.

Step Four

Now that the yellowing is removed, switch the Edit pop-up menu back to Master, and drag the Lightness slider to the right to whiten and brighten the teeth. Be careful not to drag it too far or the retouch will be obvious. Click OK in the Hue/Saturation dialog to apply your enhancements. Now press Command-D (PC: Control-D) to deselect and see your finished retouch.
