Hi TeeCee,
I'm so sorry for all of your Dad's troubles. You know, if you get the right kind of steak your Dad should be able to eat it even without teeth. My husband's teeth were pulled back in 2005, before his treatments started. Since then, he has had a full set of dentures, but he never used the bottom teeth. They never fit right or stayed in. And, actually, he could eat better without them. This was last year, before his 4th cancer. He could eat pretty much anything, even Polish Sausage, his favorite! Get a really good, aged Filet Mignon, grill medium rare, and let him at it! Tiny bites, follow with lots of water.
I am hoping that he has had a swallow atudy done and knows he will not aspirate!
Good luck to you and your Dad,
Lori
