Teeth occupy a remarkably dense symbolic territory within the depth-psychological corpus, drawing commentary from analysts, mythographers, and phenomenologists of the body alike. The most concentrated theoretical statement comes from Jung, who reads the loss of teeth as the loss of one’s ‘grip’ — invoking the etymological kinship between the German Begriff (concept, notion) and the Latin conceptio, both of which figure understanding as a grasping or seizing. Teeth are thus the somatic ground of cognitive appropriation: to lose them is to lose a hold on reality, relationship, or self-control. Abraham extends the register into libido theory, positioning the eruption of teeth as the inaugural moment of oral sadism, making the tooth the first instrument of world-destruction available to the infant, prior even to the hand. Neumann approaches the same archaic stratum from the side of the Terrible Mother, documenting how the toothed vagina — the vagina dentata — encodes the devouring feminine as a mythological universal, and how the heroic masculine must break those teeth to transform the devouring other into a woman. Mythological resonance extends further: Harrison and the Alchemy tradition both register the dragon’s teeth as generative — sown like seed, they produce armed warriors, linking dental imagery to chthonic fertility and martial rebirth. Across these registers, teeth mark the threshold between eating and being eaten, between conceptual grasp and dissolution.
