[Dental treatment in old age-When and what is indicated?]

In the past few years the oral health of seniors has improved and more seniors retain their natural teeth until old age; however, the prevalence of oral diseases among seniors is still very high and a serious problem. Good oral health is, however, relevant for seniors as it influences the chewing function, the nutritional status and general satisfaction. In addition, diseases of the oral cavity show interactions with general health. The current article therefore provides an evidence-based overview of the oral health of seniors and highlights important relationships (nutritional status, oral health-related quality of life, general health). It also gives advice on when dental treatment may be indicated. Furthermore, instruments for assessing oral health, chewing function and oral health-related quality of life are presented and explained.
