Periodontal disease, a serious gum infection that damages the soft tissue and destroys the bone that supports your teeth, has long been known to cause oral health issues. But did you know that periodontal disease can also have a significant impact on your overall health? One of the more concerning links is between periodontal disease and increased blood sugar levels, especially in individuals with diabetes or those at risk of developing the condition. This article explores how periodontal disease can lead to higher blood sugar and why managing oral health is critical for people with diabetes.
Understanding Periodontal Disease
Before diving into how periodontal disease affects blood sugar, it’s important to understand what periodontal disease is. It typically begins with gingivitis, which is the inflammation of the gums caused by the accumulation of plaque — a sticky, colorless film of bacteria that forms on teeth. If left untreated, gingivitis can progress to periodontitis, a more severe form of the disease where the inflammation affects the tissues surrounding the teeth and the underlying bone.
As periodontitis advances, the infection can spread deeper into the gum tissue, causing pain, swelling, bleeding gums, tooth mobility, and in extreme cases, tooth loss. Periodontal disease can also lead to systemic complications, affecting other areas of the body, including the heart, lungs, and the metabolism, leading to elevated blood sugar levels.
The Connection Between Periodontal Disease And Blood Sugar
Research has shown a bidirectional relationship between periodontal disease and diabetes. This means that not only can periodontal disease contribute to higher blood sugar, but high blood sugar can also make gum disease worse. To understand how periodontal disease can lead to higher blood sugar, we need to look into the mechanisms that link these two conditions.

1. Inflammation and Insulin Resistance
The primary way in which periodontal disease influences blood sugar is through inflammation. When the gums become infected, the body mounts an inflammatory response to fight the infection. Inflammation is a complex process that involves the release of various immune system chemicals, including cytokines, which are signaling molecules that help regulate immune responses.
However, in the context of periodontal disease, the inflammation is chronic and can spill over into the bloodstream. One of the key cytokines produced during this chronic inflammation is interleukin-6 (IL-6), which is known to contribute to insulin resistance. Insulin resistance occurs when the body’s cells become less responsive to the action of insulin, a hormone that helps regulate blood sugar levels.
As insulin resistance worsens, the pancreas must produce more insulin to keep blood sugar levels stable. However, over time, the pancreas may struggle to keep up with this demand, leading to higher blood sugar levels. This cycle can make it more difficult for people with periodontal disease to control their blood sugar, especially if they have diabetes.
2. Bacterial Toxins and Systemic Effects
The bacteria that cause periodontal disease can release toxic byproducts into the bloodstream. These bacteria, primarily Porphyromonas gingivalis and Tannerella forsythia, produce enzymes that break down the tissues in the gums and the bones that support teeth. As these bacteria multiply, they release toxins that can enter the bloodstream and have a wide range of systemic effects on the body.
The presence of these toxins can contribute to systemic inflammation and exacerbate insulin resistance. Studies have shown that people with severe periodontal disease often have higher levels of these toxins in their bloodstream, and these levels tend to correlate with higher blood sugar and more difficulty in controlling diabetes.
3. Elevated C-Reactive Protein (CRP)
One of the common biomarkers of systemic inflammation is C-reactive protein (CRP). CRP is produced by the liver in response to inflammation, and elevated levels of CRP have been associated with insulin resistance and the development of type 2 diabetes. Periodontal disease has been shown to increase CRP levels, which can, in turn, raise blood sugar levels.
Higher CRP levels not only contribute to insulin resistance but also increase the risk of developing other health complications, such as cardiovascular disease. People with both periodontal disease and diabetes tend to have higher CRP levels, which can create a vicious cycle of inflammation and metabolic dysfunction.
4. Impact on Blood Vessels and Circulation
Another mechanism by which periodontal disease can affect blood sugar is through its impact on the blood vessels. Chronic inflammation from gum disease can contribute to the thickening of the blood vessel walls and the buildup of plaque in the arteries, a condition known as atherosclerosis. This can impair blood circulation and make it harder for insulin to be efficiently delivered to cells throughout the body.
When the blood vessels are damaged by inflammation, the body’s ability to regulate blood sugar becomes more difficult.
Insulin needs to be transported effectively to the cells, and any disruption in circulation can hinder this process, leading to higher blood sugar levels.
The Bidirectional Relationship Between Periodontal Disease And Diabetes
The relationship between periodontal disease and blood sugar is not one-sided. Just as periodontal disease can increase blood sugar levels, high blood sugar from diabetes can worsen gum disease. When blood sugar levels are elevated, the body’s ability to fight off infections, including those in the gums, is compromised. This makes it easier for bacteria to proliferate and cause gum disease.
Furthermore, people with uncontrolled diabetes often experience dry mouth, a condition known as xerostomia, which reduces the amount of saliva in the mouth. Saliva helps wash away food particles and neutralizes acids produced by bacteria in the mouth. With less saliva, the risk of plaque buildup and the progression of periodontal disease increases.
Managing Periodontal Disease to Control Blood Sugar
The good news is that managing periodontal disease can help improve blood sugar control. Proper oral hygiene practices, such as brushing twice a day, flossing, and using mouthwash, are essential for preventing and controlling gum disease.
Regular dental check-ups and cleanings are also important, as a dentist can remove plaque and tartar that build up in hard-to-reach areas.
For individuals with diabetes, it’s particularly important to monitor blood sugar levels and maintain a healthy lifestyle.
Eating a balanced diet, exercising regularly, and taking medications as prescribed can help manage blood sugar and reduce the severity of periodontal disease.
In some cases, more advanced treatments for periodontal disease may be necessary. This may include scaling and root planing, which are deep cleaning procedures that remove bacteria and infected tissue from beneath the gums. In severe cases, surgery may be required to restore the health of the gums and bone supporting the teeth.
Conclusion
The connection between periodontal disease and elevated blood sugar is well-established and operates through various mechanisms, including chronic inflammation, bacterial toxins, and the impact on insulin resistance. Periodontal disease can make it more difficult to control blood sugar, especially in individuals with diabetes, and can contribute to the worsening of insulin resistance over time. Conversely, high blood sugar can exacerbate gum disease, creating a vicious cycle of poor health.
Managing oral health is an essential component of overall health, particularly for individuals with diabetes. By maintaining good oral hygiene, seeking regular dental care, and controlling blood sugar, it’s possible to reduce the risk of both periodontal disease and the complications associated with high blood sugar.
