Facial sagging/loss of musculature due to tooth loss and extractions - can this be corrected? (photo)

I agree with the oral surgeon that removing the 2 wisdom teeth and replacing the second molar with an implant should not change your face. It appears as if your right side jaw bone is longer and more angled than the left side. Your chin even seems to be off center to the left. Unless you had jaw surgery on the left and had substantial bone removed or if your left condyle(jaw joint)is being eaten away by arthritis or a tumor,  this seems to be something that happened in your growth and development. The right side developed normally and the left side did not. I would check with an oral medicine/TMJ specialist or the dental school if you have one near you.
