The tooth occupies a surprisingly rich and multi-layered position within the depth-psychological corpus, drawing together oneiric symbolism, oral-phase libido theory, mythological motif, and primitive belief about the life-substance. Freud treats the tooth primarily within the register of dream-interpretation: the classic ‘dental stimulus dream,’ exhaustively analyzed in The Interpretation of Dreams and revisited in the Introductory Lectures, links tooth extraction to masturbation, puberty, and the displacement of genital material upward along the body axis. This interpretive tradition is further developed by the Rank contribution Freud cites, grounding tooth symbolism in the castration complex and in the broader economy of sexual repression. Jung, characteristically, relocates the tooth from libidinal dynamics to the symbolic order of grip, grasp, and conception: losing a tooth in a dream signifies losing one’s hold on reality, relationship, or a valid opinion, a reading that moves through the etymological kinship of ‘grip’ with German Begriff and Latin conceptio. Karl Abraham’s contributions situate the tooth within the developmental schema of oral sadism — teeth as the infant’s first instruments of aggression against the world, primary vehicles of destructive impulse before the hands assume that role. Beyond the clinical literature, the tooth appears in mythological register: Harrison documents the sowing of the dragon’s teeth by Kadmos and Jason; Berry reads the Graiai’s single shared tooth as a divinatory implement, language cut from nature itself. These strands — the oneiric, the developmental, the mythological — constitute the contested and generative field this term inhabits in the corpus.
