Oral frailty is an important factor that affects physical frailty and health. Because oral diseases are a process of gradual evolution over time, many elderly people think poor oral status is a normal part of aging and therefore ignore the discovery and treatment of oral frailty problems. Greater emphasis placed on physical frailty assessment in clinical care, means the assessment of oral frailty is often inadequately addressed leading to the problem of limited early detection of oral frailty cases. This paper conducts a literature review examining the definition, precipitating factors and assessment of oral frailty. Identified and discussed are important aspects of oral care including the referral, food selection, care of dry mouth, oral-motor exercises and prevention strategies for oral frailty. It is hoped that through this paper medical staff gain new knowledge of oral frailty assessment and care, and integrate oral frailty assessment into clinical care so as to improve the overall care quality for clinical clients.
