A recent case report highlights the severe systemic consequences of poor oral health, illustrated by the death of a 65-year-old man due to untreated dental caries that led to a deep neck infection, sepsis, and heart failure. Despite initial non-specific symptoms and extensive testing, identifying the source of infection proved difficult until a dental consultation revealed multiple tooth issues. The case underscores the life-threatening nature of oral diseases and advocates for early dental interventions to prevent such outcomes. Researchers emphasize the importance of integrating oral health into overall patient care.
