Interdisciplinary Strategies for Improving Oral Health in Older Adults: A Comprehensive Review

Oral health in older adults is a critical component of overall well-being requiring integrated, interdisciplinary approaches to address its complex interplay of medical, functional, and psychosocial challenges. The aim of this is to examine strategies to enhance interdisciplinary collaboration among dental professionals, physicians, nurses, nutritionists, and caregivers to improve oral health outcomes in aging populations. Older adults commonly face dental problems such as periodontal disease which can be exacerbated by polypharmacy, systemic diseases, and barriers to accessing care. These multifaceted needs necessitate coordinated efforts across dentistry, geriatric medicine, nursing, and social support systems. Strategies of effective interdisciplinary care include: (1) Medical-dental integration, enabling physicians to screen for oral health issues during routine assessments; (2) Nursing and caregiver engagement in daily oral hygiene support and early problem identification; (3) Nutritional interventions tailored to address chewing difficulties and prevent malnutrition; (4) Social support systems to improve access to affordable care; and (5) Technology-driven solutions such as tele-dentistry to enhance communication, early detection, and care coordination. Despite these opportunities, systemic barriers persist, including fragmented healthcare systems, financial constraints, workforce shortages, cultural biases, and technological gaps. Progress requires commitment from policymakers, healthcare institutions, and health care professionals to prioritize geriatric oral health as a public health imperative. In conclusion, interdisciplinary collaboration enhances older adults' oral-systemic health via cross-sector policies and healthcare workforce education. Implementing these strategies can mitigate oral health disparities, reduce the burden of chronic diseases, and improve quality of life for aging populations through holistic, patient-centered care.
