This disparity in the correlates of TD existed despite a small but significant relationship between psychological distress and dental irritation. Conversely, TD were unrelated to psychological distress, whereas other dream types were (specifically, dreams of being smothered and dreams of falling). TD were related to dental irritation (specifically, tension sensations in the teeth, gums, or jaws upon awakening), whereas other dream types were not. Dream themes, dental irritation, psychological distress, and sleep quality were assessed among 210 undergraduates. The aim of the present study was to explore two possible hypotheses for the origin of TD specifically, TD as incorporation of dental irritation into dreaming, and TD as a symbolic manifestation of psychological distress. They are especially enigmatic as they do not readily fall under the rubric of the "continuity hypothesis", i.e., dreams of current and salient waking-life experiences. Teeth dreams (TD), i.e., dreams of teeth falling out or rotting, are one of the most common and universal typical dream themes, yet their source remains unknown and they have rarely been studied empirically.
