Reconstruct jaw and replace teeth

My husband has raised 4 children has 8 grandchildren and has been a person who would help anyone. He served 34 years in the national Guard and went to Afghanistan, Egypt, Panama, Turkey and Germany. Proudly and was always willing to go wherever needed. His civilian job was 25 years in law enforcement and corrections. He did dip tobacco they gave it to him free from 17 in the National Guard. He has recently had to have multiple procedures to get rid of the oral pre cancer condition. They used lasers and said it would go away. However after 3 attempts they had to remove all teeth and then a 1/4 of an inch of his jaw bone upper and 1/4 of an inch lower jaw bone. This makes it almost impossible to obtain normal dentures due to the excess gap. We were told no one dies from not eating. They said around 26000.00 ballpark figure to cover the facial and jaw reconstruction skin grafts and implants for dentures to hang onto. We have no money for this he has not had a solid food in over 7 months he is miserable we pulled together 1600.00 for the molds and lab fees but are not guaranteed they can fix jaw enough to wear a set of dentures but we have to pay the 1600 lab fee just to see if it will work. I have leukemia and it is not about me but my meds are astronomical and we hate asking for help. Please find it in your heart to help him. Please help him he has always given his last dollar if he had one.
