Potential Mechanisms of Phantom Tooth Pain
Phantom tooth pain could potentially be a manifestation of an unusual neuropathic pain disorder. Examples of neuropathic pain disorders include reflex sympathetic dystrophy, neuroma, and nerve compression pain. Some suggest that those neuropathic pains that have a predominantly central “generator” comprise the so-called deafferentation pain syndromes (Portenoy, 1991). This theory does not exclude the possibility that a peripheral lesion is required to sustain the pain resulting from the central generator (Devor et al.,1991) (Fig. 1).
