There is research indicating that periodontitis may be associated with several other health conditions such as heart disease, diabetes or stroke.1,2 

However, saying that two conditions are associated is not the same as saying that one causes the other.

For example, studies have shown that more people who have gum disease have or experience one of the conditions mentioned above than people without gum disease.1-4  This finding, though, could be the result of another factor,4 like smoking; people who smoke are at higher risk for heart disease and stroke as well as gum disease.

Well-designed clinical trials are needed to establish whether a cause-and-effect relationship exists and to determine if, or how, treating gum disease may affect overall health.
