Until fairly recently, dentistry was treated as a completely separate (and to some, even unrelated) field from medicine. People would never dream of talking about their oral health with their general practitioner, or about their overall health with the dentist. Now we know better, and more and more research is proving the strong and important link between oral health and whole body health. It is becoming more commonplace to hear of the link between the two fields, but there is still much to educate patients about. One of the most studied and important links is between oral health and cardiac health.
