How to Whiten Teeth in GIMP?

Step 1:

Step 3:

Click on the Duplicate icon at the bottom of the Layers panel to make a copy of the layer.

This will duplicate the selected layer so that we can compare it with the original portrait and even if we do any mistake we do have a fresh image layer to rework on.

Step 4:

Click on Colors and select the Hue/Saturation option.

Step 5:

Reduce the saturation level to around -50 and increase the lightness in your image layer to 5. Remember to not do any drastic changes in the saturation and lightness level. Anything severe can make the picture look fake.

This will make your teeth whiter, but we still need to enhance them to mold them to look more realistic.

Update the brush selection to Feather. You can now drag the brush onto the selected area and it will brighten up the selected areas evenly with softer strokes.

The softness of the brush must be selected according to the portrait selected and the desired output. As you don’t want an unnatural picture.

Step 7:

Select the gums and the spaces between your teeth. We need to brighten these areas as well so that it matches with each tooth’s brightness. Duplicate the selected area to perform any edits to it.

Step 8:
