A long-term study in Japan has found an association between certain gum problems and an increased risk of dementia. People who experienced gum bleeding were 56% more likely to develop dementia and 61% more likely to develop Alzheimer’s disease compared with those who had lower levels of gum bleeding.

According to the Journal of Clinical Periodontology, researchers followed the oral health and cognitive function of nearly 1,400 adults in Japan over a period of 10 years.
Indicators Linked to Dementia
The study found that participants with the most severe gum recession were 59% more likely to develop dementia, while deeper pockets between the teeth and gums were associated with a 72% higher risk.
These conditions are commonly associated with gum disease and inflammation. Researchers suggested that there may be a connection between oral health and inflammatory processes linked to cognitive decline.
Chronic inflammation may affect the blood-brain barrier and could potentially contribute to neuroinflammation and damage to nerve cells. However, researchers noted that these possible mechanisms require further investigation.
The Study Does Not Prove a Causal Link
Despite the long follow-up period, the study was observational, meaning it identified statistical associations but did not prove that gum disease directly causes dementia.
The study recorded 267 cases of dementia of different types, including only 51 cases of vascular dementia. This limited the researchers’ ability to determine how oral health may be related to specific types of dementia.
The researchers called for larger and more diverse studies to confirm the findings and determine whether oral health could serve as an indicator of future cognitive decline.
Overall, the findings highlight the importance of maintaining healthy teeth and gums, but oral health should not currently be considered a proven method of preventing dementia.
