Just like the Bright Eyes Trick,
you should never make theeths pure white. Here is how to turn
a smile into a bright smile!
1.
Select the teeth using the Magic Wand
and Feather (CTRL+ALT+D)
2.
Open the Hue/Saturation Menu (CTRL+U),
change the Edit field to "Yellows", bring down the Saturation
level and boost the Lightness a bit (not too much or it won't
look natural).
and Feather (CTRL+ALT+D)
