In 2025, oral health became a crucial part of understanding overall health. Dr. Thomas Van Dyke emphasized this shift at a recent dental conference, noting that dentists and doctors have long operated in separate realms. However, new research shows that what happens in our mouths can affect our entire bodies.
During a discussion on how oral health connects to systemic diseases, Van Dyke observed a change in attitudes. He reminded us that dentists often view themselves as specialists of the mouth, but specialists in inflammatory diseases are paying closer attention to oral health connections.
Yet, experts caution that the exact nature of these links is still being studied. Dr. Paul J. Allison from McGill University pointed out that while many studies show associations between oral health and systemic diseases, the causal relationships are not always clear. Still, periodontal disease might indicate wider health issues tied to inflammation.
Significant changes in oral health behaviors were seen recently. Data from the Canadian Health Measures Survey showed that Canadians are keeping more of their teeth compared to 15 years ago. However, indications of gum disease have worsened, raising concerns.
Here are some key findings from 2025 that highlight the connection between oral health and systemic diseases:
Flossing and Stroke Risk
A U.S. study linked regular flossing to lower stroke risks. Those who flossed at least weekly had a 22% lower risk of ischemic stroke and a 44% lower risk of a specific type of stroke. Dr. Souvik Sen explained that regular flossing could reduce inflammation, which is linked to cardiovascular issues.
Dementia and Oral Health
In February, researchers proposed that poor oral health might significantly increase the risk of dementia. A study found that older adults with gum disease who received treatment experienced slower cognitive decline and a 38% lower risk of developing dementia.
Gum Disease and Cancer Risk
A July study revealed that gum disease could raise the risk of gastric cancer by up to 25%. This research emphasized the need to promote dental health to prevent serious health issues.
Tooth Loss and Mortality
A study published in October found that losing teeth could be related to a higher risk of death in older adults. The speed of tooth loss appeared to be a critical factor, with faster loss linking to significantly higher mortality risks.
Parkinson’s and Oral Bacteria
In September, researchers discovered a connection between a specific oral bacterium and Parkinson’s disease. The study showed that this bacterium might harm neurons linked to the disease, opening new paths for understanding the condition.
Root Canals and Metabolic Health
By November, findings from King’s College London indicated that successful root canal treatments could improve blood sugar control and reduce inflammation. This highlights how dental health professionals can impact broader health issues.
The evidence is growing, showcasing that our oral health plays a larger role in overall health than we previously thought. As research continues, it is clear that good oral hygiene is not just about having a bright smile—it’s crucial for our long-term health.
