A patient's mouth can literally serve as a window to their overall health. Systemic conditions that are common among many older patients, such as diabetes, often have oral manifestations. What are some of the symptoms to look for, and how can we promote and preserve the oral health of vulnerable patients? Dr. Douglas Berkey, professor at the University of Colorado Schools of Dental Medicine and Public Health, where he also serves as co-director of the Center on Aging, discusses some of the most common oral health problems among elderly and long-term care residents, including oral abscesses and periodontal disease, and suggests a proactive approach to dental care for these patients. Dr. Eric Tangalos hosts.
