Health issues for sammies that have been debarked

My boy sammi, bundy, is eight years ok almost nine. I have had him for close to five years now. His previous owners debarked him. Bundy had surgery recently for a growth on his eyelid and I asked the vet about his thrust because he seems to gag a bit. She said his throats was badly scarred but there was nothing that could be done. His gagging seems to really be getting worse. Does anyone have any ideas about how I can make life easier for him. He’s a beautiful big doona on legs and I hate what happened to him. Tks
