In this tutorial, we learn how to whiten teeth in the Gimp image editor. First, open up GIMP and zoom in on the teeth of your image. From here, create a new layer named "white", making sure it's transparent. Now, make sure the white tab is on the top and go to "mode" then "saturation". Select the brush named "circle fuzzy 19". Put the scale around 1.5 or 1.6 and then draw on the teeth, which will make them white! Do this for all of the teeth, then when you save you can use this as your image with white teeth.
