Loss of teeth and the bone around them and reduced periodontal health might increase the risk of ischemic stroke. Previous studies have suggested a relationship between periodontal (gum) disease and stroke, a private TV channel reported.
After the adjustment for age and tobacco use, people who were completely edentulous (toothless), partially toothless and/or had significant clinical attachment loss were significantly more likely to have a history of stroke than those with teeth and no appreciable attachment loss. The likelihood of having had a stroke was about twice as high in those with complete tooth loss or extensive gum disease as among those with good oral health.
The researchers point out that it is unclear whether periodontal disease is an independent risk factor for stroke or a risk marker for the disease. Chronic inflammation arising from dental disease has been implicated in the development of atherosclerosis or hardening of the arteries - a key risk factor for stroke.
