Or a dry wheel grate on the axle-tree;
And that would set my teeth nothing on edge,
Nothing so much as mincing poetry:
'Tis like the forced gait of a shuffling nag.

從字面上看，"set one's teeth on edge"意思是造成不愉快的牙齒刺痛。更普遍的是用來描述任何不愉快的厭惡感覺。

早期說法是“to edge the teeth”,描述像吃生大黃(rhubarb一種蔬菜)酸性味道造成的牙齒敏感感覺。

諺語,字面類似咬緊牙關,形象化,不過由中文的堅持意思,變了不安、緊張,類似看到千鈞一髮(1條頭髮綁着3萬斤重的東西)
