In the case presented, a 65-year-old man with multiple dental, medical, and social problems benefited from interdisciplinary assessment and treatment. Despite his poor oral-health status and oral-health behaviors upon admission, patient education and dental therapy resulted in improved daily oral hygiene, elimination of oral diseases, and improved oral function. The overall quality of life of any individual, particularly an older one, can be enhanced through oral-disease prevention, health promotion, and, when indicated, dental therapy. This patient was treated in a hospital environment with a well-established team approach to geriatric care. However, regardless of the care setting, the physician can play a key role in improving the oral health status and quality of life of older adults by including an oral screening examination as part of the periodic comprehensive geriatric assessment, recognizing oral pathology, requesting dental consultations and encouraging appropriate dental service utilization.
