From here:
"Teeth might have been a barren intellectual exercise. It was envisioned as a prism through which to explore the baffling continued existence of myth in a post-modern, post-Jungian world, and specifically the reemergence of the vagina dentata myth (now posing as metaphor) in a post-Camille Paglia Sexual Persona world.

The film receives its bonafides as cultural commentary by the writer/director Mitchell (son of Pop artist Roy) Lichtenstein’s close reading of Paglia’s interpretation of the phenomenon. Lichtenstein first heard of the myth while an undergraduate at Bennington. When Dawn, his heroine, goes online to research whatever is “going on down there,” she exposes us all to Paglia’s take on the violence inherent to penetrative sex."
