The Latin expression vagina dentata defines one of the most ancient archetypes of mankind: mythical representations of female genitalia equipped with ferocious dentition can be found in very different cultures and traditions.
In what can be read as an early warning against the dangers of the vagina, Hesiod recounts how, even before being born, Chronos castrated his understably surprised father Uranus from inside his mother Gaia’s vulva. In many other mythological tales, the hero on his quest has to pass through the gigantic vagina, armed with teeth, of a goddess: this happens in the Maori foundation myths, as well as in those of the Chaco tribes of Paraguay, or the Guyanese people. From North America populations to South East Asia, this monstrous menace was a primal fear. In Europe, particularly in Ireland and Grat Britain, cathedrals and castle fortifications sported the Sheela na Gig, gargoyles showing oversized, unsettling vulvas.
As you can guess, this myth is linked to an exquisitely masculine unconscious terror, so much so that Sigmund Freud interpreted it as a symbol of castration anxiety, that fear every male adolescent feels when first confronted with the female reproductive organ. Others see it as an allegory of the frustration of masculine vigor, which in a sexual intercourse enters “triumphantly” and always leaves “diminished”. In this sense, it is clear how the vagina dentata might be related to the ancient theme of the puella venenata (the “poisonous girl”), to other myths such as the succubus (which was perhaps meant to explain nocturnal emissions), and female spermophagus figures, who feed on men’s vital force, as for example the Mesopotamian demon Lilith.
The history of the vagina dentata, which was sometimes told to children, could have also served as a deterrent against molesters or occasional sex. Even in recent times, during the Vietnam War, a legend circulated among American troops regarding Viet Cong prostitutes who allegedly inserted razor blades or broken glass in their intimate parts, with the intent of mutilating those unwary soldiers who engaged in sex.
What few people know is that, in a purely theoretical way, a toothed vagina could be biologically possible. Dermoid cysts are masses of specialized cells; if these cells end up in the wrong part of the body, they can grow hair, bones or teeth. Inguinal dermoid cysts, however, do not localize in the vaginal area, but usually near ovaries. And even in the implausible scenario of a complete dentition being produced, the teeth would be incapsulated inside the cyst’s own tissue anyway.
Therefore, despite stories on the internet about mysterious “medical cases” of internal cysts growing teeth that pierce the uterus walls, in reality the vagina dentata remains just a fascinating myth.
As expected, this uncanny idea has been exploited in the movies: the most recent case is the comedy horror film Teeth (2007, directed by M. Lichtenstein), the story of a young girl who finds out her private parts behave rather aggressively during intercourse. Less ambitious, and more aware of the humorous potential of its subject matter, is the Japanese B-movie Sexual Parasite: Killer Pussy (2004, by T. Nakano).
In Tokyo Gore Police (2008, by Y. Nishimura) a mutant girl grows a crocodile mandible in place of her thighs:
Many great authors have written about vagina dentata, including the great Tommaso Landolfi, Stephen King, Dan Simmons, Neil Gaiman, Mario Vargas Llosa and others.
