Though the teeth, the tongue, and the mouth make up only a small part of the body, an issue with any of them can influence your health. A recent study found a definitive connection between oral health disease and heart disease and stroke. According to the results of the study, the plaque that builds up around the teeth or due to gingivitis can release bacteria into the bloodstream. This bacteria in turn travels to the heart and can cause a blockage. This is why regular dental treatment is crucial.
