Jason Y1 - 2021 N1 - T2 - The Atlas of Emergency Medicine, 5e AB - Methamphetamine-induced caries (MIC) is hypothesized to be caused by the combination of mental and physiologic side effects of methamphetamine (MA) use such as xerostomia (dry mouth), gingival inflammation, poor oral hygiene, and frequent ingestion of high-sugar carbonated beverages (for relief of dry mouth). The appearance of MIC is characteristically smooth and dark in color; caries tend to start near the gingiva and can progress to the complete destruction of the coronal portion of the tooth (see also Figs. 17.4 and 17.5). Patients with MIC may not experience dental pain because MA can block the expected odontalgia. In addition, MA users tend to clench or grind teeth (bruxism), resulting in severe dental wear patterns, trismus, cracked teeth, disorders of the TMJ, and myofascial pain.
