The findings of the new study states that, tooth loss on the account of gum disease or cavities during the adulthood might be a sign of higher risk of death due to disease in the heart in the latter life.  The findings brought reports of previous studies that heart disease can be linked to oral health. 

Over time, there have been numerous studies that have shown disease in the gums to cause heart disease.  However,  the cause-and-effect relationship of the two is still yet to be proven existent.  Generally, tooth loss is considered to be a sign of poor oral health.
 
Scientist hypothesize or made an intelligent guess to be able to explain the link between oral and heart health, that the bacteria in the mouth can lead to cavities and gum disease may enter the bloodstream and damage the blood vessel lining directly.  The bacteria may also cause inflammation in the body, a known cause for heart disease.
