This is an old observation and at least a century long debate, when the theory of focal sepsis linked oral sepsis and dental extractions with endocarditis. Yet in recent years, this field of research has considerably intensified, and there is now a plethora of evidence for different oral-general health links. For example, periodontal (gum) disease has been consistently associated with atherosclerosis and cardiovascular disease markers,2 while number of teeth,3 and even oral health behaviours such as tooth brushing,4 have been shown to be independent predictors of mortality. These are only examples of a growing body of literature linking oral health, mostly tooth loss and periodontal disease, with a number of different health conditions particularly in the middle and older adulthood.
