My husband had stage 4 head and neck
cancer, tumor was in the very back of his
throat but due to the radiation the majority of his saliva glands are gone, he has tried everything out there and nothing works. He sometimes has a hard time swallowing bread, needs to drink all the time. Now his front teeth are looking kind of see thru like they're getting thin. Are crowns, vaneers or implants best for him? He'll probably have to have all his teeth done.
