Did you know that maintaining good oral health goes beyond just having a sparkling smile and fresh breath? Research has shown that oral health is connected to several other areas of health, including brain health, heart health, and metabolic health. Here's a look at how oral health affects these different aspects of our health:

Oral health and the brain

Poor oral health has been linked to cognitive decline and Alzheimer's disease. Research has found that individuals with gum disease have a significantly higher risk of developing Alzheimer's disease compared to those without gum disease. The mechanisms which link oral health and brain health are still under research. However, there is evidence to suggest that the bacteria that cause gum disease can travel from the mouth to the brain and potentially contribute to the development of brain diseases. Studies have found that oral bacteria, such as Porphyromonas gingivalis, can enter the bloodstream and reach the brain, where it can cause inflammation and damage to brain cells. This inflammation and damage has been linked to the development of neurodegenerative conditions.

Oral health and the heart

Oral health is also linked to heart health; several studies have shown that individuals with gum disease have a higher risk of developing heart disease. The bacteria that cause gum disease can enter the bloodstream and contribute to the formation of plaque in the arteries, which can lead to heart disease. When oral bacteria enter the bloodstream, they can trigger an immune response, leading to inflammation in the blood vessels. This inflammation can cause the arteries to become narrow and stiff, making it difficult for blood to flow through. Over time, this can lead to the development of atherosclerosis, a condition in which plaque builds up inside the arteries, increasing the risk of heart attack and stroke. Maintaining good oral hygiene can help reduce the risk of heart disease.

Oral health and metabolic health

Research has also shown that oral health is connected to metabolic health. Individuals with gum disease have been found to have higher levels of insulin resistance, which is a risk factor for type 2 diabetes. The bacteria that cause gum disease can also contribute to inflammation in the body, which is a key driver of metabolic diseases. This inflammation can impair insulin sensitivity and glucose metabolism, leading to insulin resistance and metabolic issues. Since chronic inflammation is a common feature of many metabolic diseases, such as obesity, type 2 diabetes, and metabolic syndrome, it is important to prioritize oral health to combat inflammation and metabolic disarray. What’s more, research shows that prioritizing oral hygiene improves metabolic health for those with type 2 diabetes: Researchers have found that treating gum disease in individuals with type 2 diabetes improved glycemic control and insulin sensitivity!

To conclude, maintaining good oral health is essential for our overall health and wellbeing. Research has shown that oral health is connected to brain health, heart health, and metabolic health. By practicing good oral hygiene, such as brushing and flossing regularly and visiting the dentist for regular check-ups, we can help reduce the risk of developing these health conditions. So now you know, a healthy mouth equals a healthy body!
