How Brushing your Teeth and Blood Sugar Control are Related

The systems in our body are deeply interconnected, making it easy to miss important links without proper guidance. Take, for instance, the relationship between your oral health and diabetes. This is a bidirectional relationship where each condition can influence the other. Understanding this link can help manage both your overall health and your smile.

How Oral Health Affects Diabetes

Think of your body as a complex system where everything is linked. If you have an infection in one area, it can cause problems elsewhere. This is exactly what happens with periodontal (gum) disease. Gum disease, which includes gingivitis and the more severe periodontitis, creates a state of chronic inflammation in your body.

This constant inflammation can interfere with your body’s ability to use insulin effectively, leading to higher blood sugar levels. For someone living with diabetes, this makes glucose control much more challenging. Over time, persistently high blood glucose can increase the risk for serious complications, including nerve damage (neuropathy), heart disease, stroke, kidney disease, and vision problems.

How Diabetes Affects Oral Health

The connection works in the other direction as well.

High blood sugar levels can weaken the immune system, reducing your body’s ability to fight off bacteria. This makes you more susceptible to infections, including the very gum diseases that can worsen diabetes. Furthermore, inadequate glucose control can slow down the healing process, making it harder for your gums to recover from inflammation or dental procedures.

Beyond gum disease, unmanaged diabetes can lead to other oral health issues. Many people experience xerostomia, or dry mouth, due to reduced saliva flow. Saliva is essential for washing away food particles and neutralizing the acids produced by bacteria. Without enough of it, your risk for cavities increases. Another common issue is oral thrush (candidiasis), a fungal infection that thrives in the mouths of those with high blood sugar and compromised immunity.

Taking Control: A Dual Approach to Health

The good news is that you can manage both conditions effectively with a coordinated approach. In fact, studies have shown that treating periodontal disease can lead to improved A1C and fasting blood glucose levels in individuals with type 2 diabetes.

Here are some practical steps you can take to protect both your oral health and your overall well-being:

  • Commit to Excellent Home Care: Brush your teeth twice a day for a full two minutes each time. Don’t forget to floss at least once a day to clean between your teeth, where your toothbrush can’t reach.
  • Schedule Regular Dental Visits: Professional cleanings with your dental hygienist are essential for removing plaque and tartar buildup that you can’t manage at home. These visits also allow your dental team to spot early signs of trouble. Be sure to inform them about your diabetes diagnosis and any medications you are taking.
  • Manage Your Diabetes Diligently: Work closely with your healthcare team to keep your blood sugar levels within your target range. Proper diabetes management is a powerful tool for protecting your entire body, including your mouth.

By viewing your oral health and diabetes management as two parts of the same puzzle, you can improve your quality of life and reduce your risk of complications. Your smile and your body will thank you for it. If you’d like a personalized approach to diabetes management, please speak with your Harrison Registered Nurse.
