Mental nerve neuropathy (MNN), colloquially referred to as numb chin syndrome, is an uncommon neurologic condition that may arise secondary to multiple local and systemic etiologies, and may mimic other pain conditions affecting the mandible. Early recognition of mental nerve neuropathy in conjunction with accurate etiologic identification is crucial, as early pain management may prevent the transition from an acute to a chronic pain condition. In this article, we will describe the clinical courses of 2 patients who presented to the pain clinic with chronic painful numbness in the mental nerve sensory distribution following dental extraction. ⋯ The objective of our article is to help clinicians identify and properly manage early stage mental nerve neuropathy. Moreover, we aim to advance general medical knowledge of this important pain medicine topic. During the process of preparing this article we reviewed all existing pertinent medical literature related to MNN.
