meaning

I take it to mean that her canine teeth have no pointed ends. Most people have slightly pointed canines, though not as pointed as a wolf's fangs.

You mean her teeth are in a straight line?
What about "so blond" in the second line? It means yellowish teeth?

Good way to put it.

What about "so blond" in the second line? It means yellowish teeth?


Bland. Usually means food that has little flavor. Here it means "boring".

?But it is "blond" in the text not "bland"

I would take this to mean that she has blond hair (not yellow teeth or bland, boring teeth) and resembles a Barbie doll. Her blond hair and small, harmless-looking teeth (not sharp and dangerous-looking) make her look innocent and non-threatening.

In this case "bland is good camouflage" is an idiom?

No, it's not an idiom. It's just a way of saying that if you don't want to attract attention, it's useful to look ordinary and harmless.

I have a question here. You mean "she wants to be an ordinary woman, does not attract anyone"? So if yes, why she was worried about her looking? In the second line "this" refers to "her kind of teeth"?

"She smiles again: she has such guileless teeth, asexual teeth, nothing fanged about them. She used to worry about looking so symmetrical, so blond, so Barbie, but she’s come to think of

"This" refers to "looking so symmetrical, so blond, so Barbie." She used to worry about looking ordinary, but now she thinks that it's a good thing.
