Miss Kate, thanks for the encouragement.
Found a very complete *Tongue* web site that is dental based:
Search this link:
http://www.rdhmag.com/articles/print/volume-24/issue-8/feature/the-tongue.html for: "Life without a tongue".
Quit descriptive and it sounds like very current description of the State of the Art.
Is it possible that the world of Dental Work has a functional edge on addressing this problem?
Also, I have a link to a University doctor who sounds to have developed a significant grafting/fabrication technique. I'll add a link to that later.
