Always greatly troubled me, especially after a fish bone lodged beneath my gum, and I wound up with a horrible abscess and the most terrifying experience of my life, at age 19. The experience can be told later. Here, I seek to find an answer as to why I have as long as I can remember, even as a small kid, enjoyed eating the bones found in canned Salmon. Softened to the point of harmlessness, good calcium source, ugly to look at, though, I've always wondered why the bones of fish prepared from the fresh state on our stove present danger from bones left in. I can recall expectantly awaiting a fried Blue-gill dinner my father in law was preparing. He was a life-long fisherman, adroit at "filleting" as my wife called it, removing each and every bone...... My first mouthful filled my teeth and gums with a myriad of tiny, sharp and pointed bones, feeling like steel-wool! I spat it out, and gave up. Much to everyone's consternation. Hell, I'd always pictured swallowed fish bones piercing the guts......then what? So,.....why are canned Salmon bones so easily chewed and eaten?
