Many people think of dental care as something separate from the rest of the body, but new research suggests this is not true.
A large study led by researchers at Boston University School of Public Health shows that being unable to afford dental care may raise the risk of serious health problems, including heart disease and dementia.
Dental care is not only about keeping teeth clean or preventing cavities. The mouth is closely connected to the rest of the body. When oral health is poor, harmful bacteria and inflammation can spread through the bloodstream. Over time, this may affect major organs such as the heart and brain.
In this study, researchers focused on older adults. They looked at people aged 55 and above who were part of a large health project in the United States called the All of Us study. This project collects health data from many people to better understand diseases and improve healthcare.
The scientists examined medical records and survey answers from tens of thousands of participants. They wanted to see whether people who skipped dental care because of cost were more likely to develop serious conditions later. These conditions included heart attacks, heart failure, strokes, and dementia.
The results were clear. People who could not afford dental care had a higher chance of developing all of these conditions. This suggests that missing dental visits is not just a small issue. It may have long-term effects on overall health.
One reason for this link may be inflammation. When gum disease is not treated, it can cause long-lasting inflammation in the body. This type of inflammation has already been linked to heart disease and problems with brain function.
Another reason may be that tooth loss can affect nutrition. People with missing teeth may find it harder to eat healthy foods, which can also affect their health over time.
The study also highlights a larger problem. Many older adults do not have dental insurance. In the United States, fewer than one in three people over the age of 65 have coverage for dental care. Even when coverage is available, it may not include regular checkups or preventive treatments. As a result, people may delay care until problems become serious.
The researchers found that if financial barriers to dental care were removed, a small but meaningful number of cases of heart disease and dementia could be prevented. This shows that improving access to dental care may be an important way to protect overall health.
The study was published in The Journals of Gerontology, Series A. It adds new evidence to the idea that oral health and general health are closely linked.
In reviewing these findings, it is important to remember that the study shows a connection, not direct cause and effect. Other factors, such as income, lifestyle, and existing health conditions, may also play a role. However, the results still point to a clear pattern that should not be ignored.
This research suggests that making dental care more affordable could have wide benefits beyond oral health. It could help reduce the risk of serious diseases that affect quality of life and increase healthcare costs. It also shows that simple preventive care, like regular dental visits, may play a bigger role in health than many people realize.
