Abstract The elderly population often experiences an intersection of systemic diseases and oral health conditions, reflecting the intricate relationship between general and oral health. This article explores the diverse oral manifestations of systemic diseases in the elderly, emphasizing their diagnostic significance, impact on quality of life, and management challenges. Conditions such as diabetes mellitus, cardiovascular diseases, autoimmune disorders, and malignancies exhibit characteristic oral symptoms, ranging from xerostomia and periodontal disease to mucosal lesions and altered taste sensations. Recognizing these signs is crucial for early diagnosis and interdisciplinary care. This review underscores the need for integrated healthcare approaches to address the complex oral-systemic health nexus in aging populations.
