I had just about the biggest slickest crown you could imagine. Did one FUE, results were good but not amazing. I do think that a 2nd pass will take my crown from good to great. So basically, if you go to a good doctor, and are prepared for more than one surgery, then the crown is totally fixable. Regarding sleeping on a fresh transplant, I was actually surprised at how easy it was. I just slept carefully on my side with only the donor area in contact with the pillow.
