Oral health has long been recognized as an important factor in overall well-being, but recent research suggests a connection between gum disease and dementia.
Studies have backed up this connection—raising important questions about how maintaining good oral hygiene could help protect cognitive function.
Join us on March 26th for an insightful session exploring the essential link between oral health and dementia, featuring Tranquility Health and expert insights from Dr. Amaro. This event will provide practical tips for managing oral hygiene in individuals with dementia, emphasizing the importance of maintaining good oral care for overall health and well-being.

While the event will offer a deeper understanding of this subject, we also want to provide this overview. How is oral health connected to dementia? And why is maintaining good dental hygiene essential for long-term brain health?
How does oral health affect dementia?
The relationship between oral health and dementia has become a growing area of scientific interest.
Research suggests that chronic gum disease—also known as periodontitis—may contribute to cognitive decline and increase the risk of developing Alzheimer’s disease.
Possible connections between gum disease and dementia:
- Inflammation and brain health: Chronic gum infections can lead to widespread inflammation linked to neurodegenerative diseases.
- Bacteria in the brain: Harmful oral bacteria may get into the bloodstream and travel to the brain, potentially contributing to Alzheimer’s-related changes.
- Immune system response: The body’s reaction to gum disease may cause an immune response that impacts brain cells over time.
Understanding these links can help individuals proactively maintain oral and cognitive health.
The connection between gum disease and dementia
Gum disease is a common but preventable condition that affects nearly half of adults over 30 and increases with age.
Periodontitis is characterized by swollen, bleeding gums and potential tooth loss. It’s caused by bacteria that accumulate around the teeth and gums.
Studies have identified a potential link between gum disease and dementia, suggesting that bacteria from infected gums can enter the bloodstream and impact brain function.
One large-scale study from the National Institute on Aging found that individuals with severe gum disease were more likely to develop dementia over time.
Inflammation as a risk factor
Inflammation is a central factor in both gum disease and neurodegenerative conditions like Alzheimer’s disease.
When oral bacteria cause chronic inflammation in the gums, the immune system responds by releasing inflammatory proteins. These same proteins have been found in the brains of Alzheimer’s patients, suggesting that prolonged exposure to inflammation may contribute to cognitive decline.
The ongoing presence of inflammation in the body is believed to accelerate the progression of dementia by damaging neurons and interfering with brain function.
This makes gum disease a dental concern and a potential factor in long-term cognitive health.
The role of bacteria in cognitive decline
Another key connection between dementia and oral health is when harmful bacteria is in the mouth, such as Porphyromonas gingivalis, a leading cause of gum disease.
Research has shown that these bacteria can travel to the brain, which may contribute to the formation of amyloid plaques, one of the hallmarks of Alzheimer’s disease.
Studies have found evidence of P. gingivalis in the brains of Alzheimer’s patients, along with its toxic enzymes known as gingipains.
These enzymes were associated with brain inflammation and neuronal damage, reinforcing the connection between gum disease and dementia.
Gingivitis and Alzheimer’s: Early warning signs
Gingivitis, the mild and early stage of gum disease, is often overlooked but could be a warning sign for future health issues.
Symptoms of gingivitis include:
- Red, swollen, or bleeding gums
- Persistent bad breath
- Receding gums
- Sensitivity to hot or cold foods
Gingivitis is reversible with proper oral care. But if left untreated, it can progress to periodontitis, increasing the risk of bacteria entering the bloodstream and potentially affecting brain function.
Steps to protect oral and brain health
Since research suggests a connection between gum disease and dementia, maintaining oral health could be essential in protecting cognitive function.
Prioritize daily oral hygiene
Good oral hygiene habits help prevent gum disease and its potential impact on cognitive health.
Important steps include:
- Brushing twice a day with fluoride toothpaste
- Flossing daily to remove plaque between teeth
- Antibacterial mouthwash may reduce bacteria in the mouth
- Replacing toothbrushes every three to four months to ensure effective cleaning
Schedule regular dental check-ups
Routine dental visits allow professionals to detect early signs of gum disease before it progresses.
Dentists can also provide deep cleanings to remove plaque buildup and reduce bacteria levels.
Adults, particularly seniors, should aim for dental check-ups at least twice a year.
Manage overall health
Gum disease is influenced by overall health, so maintaining a balanced lifestyle can help protect both oral and brain health. Key practices include:
- Eating a nutrient-rich diet that supports oral health, such as foods high in vitamins C and D
- Staying hydrated to promote saliva production, which helps neutralize bacteria
- Avoiding tobacco products—they increase the risk of gum disease and cognitive decline
- Managing chronic conditions like diabetes, which can contribute to gum disease
Be aware of cognitive health signs
Since gum disease may be an early indicator of potential cognitive decline, individuals should also monitor their memory, reasoning, and daily cognitive function.
If there are noticeable behavioral changes, it may be time to discuss them with a healthcare professional.
