A new study suggests that gum disease could be linked to damage in the brain. This raises concerns about how poor oral health might affect overall health.
Researchers studied 1,143 adults, about 800 of whom had gum disease, also called periodontitis. They looked at brain scans to measure white matter hyperintensities (WMHs), which are areas of damaged white matter in the brain. WMHs are linked to problems such as stroke and memory issues.
The study found that people with gum disease had more white matter damage than those without it. Even after accounting for other health risks, people with gum disease were more likely to have serious white matter changes in their brains.
The researchers say this does not prove that gum disease directly causes brain damage. But it shows a strong connection between oral health and brain health. Chronic inflammation in the mouth may affect other parts of the body, including the brain.
Lead researcher Souvik Sen said, “Gum disease is preventable and treatable. If future studies confirm this link, taking care of your mouth could help protect the brain too.”
Gum disease is very common. In the United States, almost half of adults have some form of it. This makes the research important, as it may affect many people.
Health experts say it is important to remember that this study shows a link, not proof of cause. More research is needed to understand exactly how gum problems might affect the brain.
In the meantime, simple steps like brushing teeth twice a day, flossing, quitting smoking, and visiting the dentist regularly can protect the mouth and possibly the brain.
