Dental Caries in Older Adults: A Narrative Review for Non-Dental Providers

Dental caries is one of the most prevalent chronic diseases affecting older adults and remains an important, underrecognized contributor to pain, impaired nutrition, systemic illness, and reduced quality of life. Older adults access medical care more often than dental care, positioning non-dental clinicians to identify risk, initiate prevention, and facilitate timely referral. A narrative review of English-language literature was conducted using PubMed and Google Scholar. Search terms included “dental caries,” “root caries,” and “older adults.” Sources included original studies, clinical guidelines, consensus statements, and high-quality reviews, with an emphasis on relevance to older adults and applicability to non-dental clinicians. Dental caries in older adults commonly presents as root and recurrent decay and isstrongly associated with xerostomia, polypharmacy, chronic disease, functional impairment, cognitive decline, and limited access to dental care. The literature supports fluoride-based prevention, management of salivary dysfunction, dietary counseling, minimally invasive therapies such as silver diamine fluoride, and interprofessional care models. Non-dental providers play a critical role in screening, risk assessment, preventive counseling, symptom triage, and referral. Integrating oral health into routine medical care is an essential and achievable strategy to reduce morbidity and improve health outcomes in older adults.
