Kanji 牙 tusk, fang, tusk radical (no. 92) Similar words 無む 視し する 無視する is a straightforward verb meaning 'to ignore', while 歯牙にもかけない is a stronger, more colorful idiom implying the thing ignored is utterly beneath notice.
気き にも 留と めない 気にも留めない means 'not to mind' or 'not to pay attention', but 歯牙にもかけない carries a nuance of contempt or dismissal, treating something as worthless.
Etymology From 歯牙 (しが, 'teeth and tusks') + に + かける (to hang/put on). The image is of something so insignificant that one wouldn't even put it on one's teeth, i.e., not worth biting into or considering. The exact origin is uncertain, but it is a set idiomatic phrase.
