Is toothlessness a sign of heart disease?

Gum disease is a common cause of tooth loss and gum disease-related inflammation which has been found to play a role in the narrowing of the arteries. Lead study author, Dr. Ola Vedin, said, “While we can’t yet advise patients to look after their teeth to lower their cardiovascular risk, the positive effects of brushing and flossing are well established. The potential for additional positive effects on cardiovascular health would be a bonus.”

The study looked at over 15,000 heart disease patients from 39 countries that were assessed for tooth loss and followed on average for 3.7 years.

Researchers found that patients with the fewest teeth were smokers, female, less active and had higher rates of diabetes, high blood pressure, more body fat and lower levels of educations.

After adjusting for other contributing factors to heart disease, tooth loss was found to increase the risk of major heart events by six percent along with the risk of death by 15 percent.

Those with no teeth had a 27 percent higher risk of all major cardiovascular events in comparison to those with their teeth. Toothlessness was also associated with an 85 percent higher risk of cardiovascular death, 81 percent higher risk of death from all causes and 67 percent higher risk of stroke.

Vedin added, “The risk increase was gradual, with the highest risk in those with no remaining teeth. For example the risks of cardiovascular death and all-cause death were almost double to those with all teeth remaining. Heart disease and gum disease share many risk factors such as smoking and diabetes but we adjusted for these in our analysis and found a seemingly independent relationship between the two conditions.”

“This was an observational study so we cannot conclude that gum disease directly causes adverse events in heart patients. But tooth loss could be an easy and inexpensive way to identify patients at higher risk who need more intense prevention efforts,” Vedin concluded.
