Teeth Whitening would be a FANTASTIC tool to add to the Retouch panel. AI would select the teeth. Controls for both brightness and saturation would be ideal.
Current workaround
Manually painting a mask on the teeth and then manually applying adjustments.
This is definitely one of those things that would be great for a quick slider and ai selection. However, anyone that wishes they had this now - make a new layer, mask over teeth and gums loosely, select the color editor eye dropper and select a tooth, check the view selection checkbox, so you can see hues are selected, narrow your hues to eliminate the gums and lips, use the the HSL sliders to adjust the teeth to your preference.
Yes it's a lot more work than a slider, but you can improvise until the retouch panel is updated with the feature!
