What can I do to reduce my gummy smile? (photos)

I show too much of my gums when I smile. I have gotten 3 gingivectomies, but I still have swollen gums despite the surgeries and despite proper care of the gums and teeth. I am not sure what I can do to lessen the problem; I am considering jaw surgery, but I am not certain that the excess of jaw bone is that extreme. Also, I do not want to go through the extensive recovery process. Is there anything I can do to at least mask the swollen gums?
