The case of a diabetic patient hospitalized with a discharging ulcer sinus in the maxillary area and poor oral hygiene related to mucormycosis were shown and discussed in this study. A 52-year-old man with uncontrolled diabetes was referred to a tertiary care hospital with a two-year history of headaches, toothaches, nasal obstruction, and head heaviness. Recurrent URI and side face discomfort are also common. The patient was observed with ulcer sinus drainage and left maxillary pain. In the upper second and third molar regions, there is a blackish discoloration. A histological examination showed fungal hyphae after he had surgical debridement. Amphotericin B was used as a systemic antifungal. Sinonasal mucormycosis is a disease that is currently poorly understood and has a significant fatality rate. Currently, the trifecta of physician awareness, rapid initiation of therapy, and timely surgical intervention represents the most successful method of illness management.
