Research presented to the American Heart Association has found that losing two or more teeth during middle age is associated with increased cardiovascular disease risk. Studies have shown that dental health problems, such as periodontal disease and tooth loss, are related to inflammation, diabetes, smoking and consuming less healthy diets.
Studies have shown that dental health problems, such as periodontal disease and tooth loss, are related to inflammation, diabetes, smoking and consuming less healthy diets, according to study author Lu Qi, professor of epidemiology at Tulane University in New Orleans.
"Previous research has also found that dental health issues are associated with elevated risk of cardiovascular disease," Qi said. "However, most of that research looked at cumulative tooth loss over a lifetime, which often includes teeth lost in childhood due to cavities, trauma and orthodontics. Tooth loss in middle age is more likely related to inflammation, but it hasn't been clear how this later-in-life tooth loss might influence cardiovascular disease risk."
They found:
- Among the adults with 25 to 32 natural teeth at the study's start, those who lost two or more teeth had a 23 percent increased risk of cardiovascular disease, compared to those with no tooth loss.
- The increased risk occurred regardless of reported diet quality, physical activity, body weight and other cardiovascular risk factors, such as high blood pressure, high cholesterol and diabetes.
- There wasn't a notable increase in cardiovascular disease risk among those who reported losing one tooth during the study period.
- Cardiovascular disease risk among all the participants (regardless of the number of natural teeth at the study's start) increased 16 percent among those losing two or more teeth during the study period, compared to those who didn't lose any teeth.
- Adults with less than 17 natural teeth, versus 25 to 32, at the study's start, were 25 percent more likely to have cardiovascular disease.
"In addition to other established associations between dental health and risk of disease, our findings suggest that middle-aged adults who have lost two or more teeth in recent past could be at increased risk for cardiovascular disease," Qi said. "That's regardless of the number of natural teeth a person has as a middle-aged adult, or whether they have traditional risk factors for cardiovascular disease, such as poor diet or high blood pressure."
The preliminary research was presented at the American Heart Association's Epidemiology and Prevention | Lifestyle and Cardiometabolic Health Scientific Sessions 2018, a premier global exchange of the latest advances in population based cardiovascular science for researchers and clinicians.
