My 40 year old husband went through jaw surgery twice in the past 10 months. He had all of his teeth removed, top and bottom, due to a tumor , benign, found in the lower left mandible causing his teeth to rot and no bone left to hold them in. The 1st surgery he had to rebuild the jaw bone, after tumor removal, was not completely successful with the cadaver not completely taking, so there was a 2nd surgery were the took a piece of his hip bone to add to the jaw. He has healed nicely and will be receiving his implants teeth son. However, about a month after all of this started his face started flaking off and his beard falling out in patches. When it finally grows back in the patches it is completely white. He is already conscious of his temporary dentures and this condition is making him really conscious. What is this and what should he be doing to care for it?
