There are often cases when the image on your photo could use some teeth whitening. To do this you need firstly to zoom in to your model’s teeth and grab the Laso tool from your photoshop toolbar.

With laso tool selected start drawing the outline of the teeth. Use the shift key to correct the parts of the teeth you have missed and expand the selection. When your selection is ready zoom out and hit ctrl+alt+D, this will open the Feather Selection dialogue box, and choose to feather this by 1 pixel. This way you will avoid the rough edges on your selection.

In order to whiten the teeth select the Curves Adjustment Layer, on the diagram that will open put your pointer in the middle and the input about 135 and the output to 132. So using the laso, then feathering the selection and using the curves adjustment layer is a quick way to whiten the teeth on the models of your images.
