In Franz Kafka's "The Metamorphosis," Gregor Samsa finds it striking that even amidst the many sounds associated with eating, the noise of chewing teeth stands out. This observation highlights the essential role teeth play in the act of eating, emphasizing the necessity of having them to properly engage in this fundamental activity.

Gregor's reflection on this detail symbolizes a loss of agency and the harsh reality of his transformation. Despite the pleasantness of the act of eating, the absence of teeth serves as a reminder that without certain essential functions, one cannot participate in life as they once did. This further illustrates Gregor’s estrangement from his former self and the challenges he faces in his new condition.
