Poor Oral Health Can Lead to Heart Disease

It is well known that diabetes, high cholesterol, and obesity can all lead to heart disease, but what about bad teeth?

People with untreated tooth infections are almost three times more likely to develop heart problems, according to a 2016 study. Although researchers have not found a direct link to claim that poor oral health leads to heart disease, there is sufficient evidence to suggest that infections found in the mouth can be a possible contributor. This was discovered in autopsies of those who passed away from heart-related problems, where a variety of oral bacteria were found in the arteries.

How Are Bad Teeth Linked to Heart Disease?

Bacteria in the gums – Gum disease (periodontal disease) is inflammation of the gums, causing soreness, tenderness, and bleeding. Bacterial infection can enter through the gums and blood vessels connected to the heart valve. Once the bacteria reach the inner layer of the heart valve, it places pressure on the heart to pump blood, leading to a life-threatening heart condition known as bacterial endocarditis.

Tooth infection – A tooth infection, such as periapical abscess, is a pocket of infected pus that is formed in the dental pulp. The pulp house blood vessels, nerves, and connective tissues. When left untreated, the infection can spread to the heart via blood vessels, interrupting blood supply and increasing the risk of coronary heart disease.

Cavities and other types of tooth decay – Tooth decay, such as cavities, can lead to atherosclerosis or clogged arteries. This occurs as the tooth decays due to unaddressed cavities, allowing bacterial infection to enter through the gum and blood vessels. This causes blockage of blood flow as fats and other substances builds up in the artery walls, potentially leading to death or disability.

How to Prevent Heart Disease Linked to Bad Teeth?

To prevent dental infections that can lead to heart disease, doctors recommend maintaining healthy oral hygiene paired with a nutritious diet and exercise. This reduces the chances of heart disease caused by dental infections but does not eliminate the risk entirely. Genetics, alcohol, and air pollution are other known risk factors related to heart disease. Here are some helpful hygiene and lifestyle tips for maintaining healthy oral hygiene:

  • Brush and floss teeth at least twice a day.
  • Consume less sugary and acidic foods and drinks.
  • Avoid smoking and tobacco products.
  • Schedule routine dental checkups every six months.

Although poor oral health is not the number one risk factor for heart disease, doctors still recommend that patients take good care of their teeth to prevent other diseases and infections and for an overall great smile.
