The Brain

Poor oral health has been shown to be strongly associated with cognitive decline and Alzheimer’s disease. Research shows that people with periodontal disease may face a significantly higher risk of developing Alzheimer’s than those with healthy gums.

While the research is still ongoing, oral health and brain health have been shown to be connected. The evidence suggests that the bacteria/pathogens responsible for periodontal disease can travel from the mouth into the bloodstream and reach the brain. Once there, these bacteria—such as Porphyromonas gingivalis—may trigger inflammation that harms brain cells. This type of chronic inflammation has been linked to the development and progression of neurodegenerative conditions, including Alzheimer’s disease.

The Heart

Oral health is closely linked to heart health. Research has shown that people with periodontal disease have a higher risk of developing heart disease. This is because the bacteria that contribute to periodontal disease can enter the bloodstream and contribute to plaque buildup inside the arteries.

When these bacteria travel through the blood, they can trigger the body’s immune response and cause inflammation in blood vessels. Over time, plaque builds up which can narrow and stiffen the arteries, making it harder for blood to flow. This process—known as atherosclerosis—raises the risk of heart attack and stroke.

Metabolic Health

Research also shows a strong connection between oral health and metabolic health. For instance, people with periodontal disease often have higher levels of insulin resistance, which can increase the risk of type 2 diabetes. The bacteria that cause periodontal disease contribute to inflammation in the body—a major factor in metabolic issues. This inflammation can interfere with how the body processes glucose, leading to insulin resistance and other metabolic problems.

Treating periodontal disease has been shown to improve metabolic health. Research studies indicate that individuals with type 2 diabetes who receive proper periodontal care develop better blood sugar control and improved insulin sensitivity.

The Gut

Your mouth is really the gateway to your body and has a direct connection to your overall systemic health. The oral microbiome is home to approximately 700 strains of beneficial bacteria living on your gums, teeth, tongue, and cheeks. This dense ecosystem helps keep your teeth cavity-free and your gums healthy. Because your mouth is the first stop in your digestive tract, it also influences your heart, metabolism, and overall wellbeing every time you swallow.

When your mouth is unhealthy, it often signals that something is wrong. Harmful bacteria can feed on sugars in the mouth and produce acids that erode tooth enamel, increasing the risk of cavities. These bacteria can also infect the gums, leading to periodontal disease—characterized by swelling, bleeding, gum recession, and, in severe cases, tooth loss.

An overgrowth of bacteria also contributes to excessive dental plaque, the sticky film that accumulates on teeth. If not removed, plaque hardens into tartar, which can only be cleaned by a dental professional. Another common consequence of an imbalanced oral environment is halitosis, or chronic bad breath.

Maintaining good oral hygiene and regular dental visits can help control harmful bacteria and protect both your teeth and gums. Oral bacteria are not bad unless they are out of balance. For instance, harsh mouth rinses, severe dry mouth, smoking, and alcohol can wreak havoc on the oral microbiome and allow for the bad bacteria to overgrow.
