HI
@kula....I think your thin enamel and receding gums, cavities, etc., can be due to the simple process of aging. Which isn't so simple at all, by the way.
I never thought about cod fish having livers, can't imagine how you got it down, but that's OK. I'm rather up on Vit. A, and so is my husband. Still, we're older (74 and 77) and are now facing crowns that are failing b/c there is ongoing cavity beneath them, like you said, thinning enamel and gum problems (which I don't have, but Rod does). We're a dentists dream, although it's tough for them because we're the first generation that has lived as long as we have with our own teeth, there are no answers to our multiple questions. We spend a lot at the dentist's office. A not so good use of one's money. Two teeth were extracted...rotten the whole way through.
So I wonder how I could go about getting a cod liver (cod liver oil OK?) and exactly how do you treat it....cook it, that type of thing.? Anyway, good for you, I hope this simple cure will work. Thanks for the info. Yours, Lenora
