Periodontal Health and Diabetes: A Two-Way Relationship

When it comes to managing chronic conditions like diabetes, many people focus on blood sugar, diet, and medications, but your gums may be playing a bigger role than you realize. Research shows a strong two-way relationship between periodontal (gum) disease and diabetes, meaning each condition can influence the other in significant ways.

At Portland Perio Implant Center, we believe education is a critical part of prevention and management. Understanding how diabetes and gum disease are connected can empower you to protect your oral and overall health more effectively.

How Diabetes Affects Your Gums

Diabetes, particularly when not well-controlled, can compromise your body’s ability to fight infection. This makes the gums more vulnerable to bacterial plaque, the sticky film that forms on your teeth and under the gumline. Over time, this can lead to gingivitis (early gum disease) or progress into periodontitis. On this more advanced stage, the supporting bone and tissues around the teeth begin to break down.

Stages of Gum Disease

People with diabetes are not only more likely to develop gum disease, but they may also experience more severe forms of it, and healing can take longer after periodontal treatments.

How Gum Disease Affects Diabetes

The connection doesn’t stop there. Periodontal disease itself can make it harder to control blood glucose levels. The inflammation associated with gum disease produces chemicals that can increase insulin resistance, making diabetes management more difficult. In fact, studies show that treating periodontal disease can improve glycemic control in people with type 2 diabetes.

This is why we refer to the relationship as “bi-directional”: diabetes worsens gum disease, and gum disease can worsen diabetes. Comprehensive care can interrupt this cycle.

Signs of Gum Disease to Watch For

If you have diabetes, it’s essential to be extra vigilant for symptoms of gum disease, including:

Bleeding gums when brushing or flossing
Red, swollen, or tender gums
Persistent bad breath
Receding gums or teeth appearing longer
Loose teeth or changes in bite alignment

If you notice any of these symptoms, early intervention is key to preserving your oral health and potentially improving your diabetes control.

Tips for Managing Periodontal Health with Diabetes

The good news? You can do a lot to protect your gums while managing diabetes. Here are my top evidence-based tips:

Control Your Blood Sugar – This is the single most important factor. Maintaining your target glucose levels helps reduce inflammation and strengthens your body’s defense against infection, including in the gums. Work closely with your physician or endocrinologist to keep your diabetes well-controlled.
Brush and Floss Consistently – Brush your teeth at least twice a day with a soft-bristled toothbrush and fluoride toothpaste. Floss at least once daily to remove plaque from between the teeth where your brush can’t reach. If you have dexterity challenges, consider using interdental brushes or a water flosser.
Visit Your Dentist or Periodontist Regularly – Individuals with diabetes should have dental checkups every 3 to 4 months instead of the usual 6 months. These appointments facilitate early identification and treatment of gum issues before they worsen.

At Portland Perio Implant Center, we work closely with your primary dental provider and other healthcare professionals to ensure you receive customized periodontal care.
Quit Smoking – Smoking compounds the risk of gum disease and makes diabetes harder to control. If you smoke, consult your doctor about quitting strategies and resources. Your gums—and your entire body—will thank you.
Manage Dry Mouth – Diabetes and some of its medications can cause dry mouth, which increases your risk of gum disease and cavities. Stay hydrated, chew sugar-free gum to stimulate saliva, and consider saliva substitutes if needed.
Eat a Balanced Diet – A diet rich in whole foods—especially vegetables, lean proteins, and healthy fats—can support both your gum health and blood sugar regulation. Limit sugary snacks and acidic beverages that feed plaque-forming bacteria.

At Portland Perio Implant Center, we collaborate with your primary dental provider and other healthcare professionals to ensure you receive personalized periodontal care.

Why would a dentist refer you to a periodontist?

A dentist may recommend a visit to a periodontist if they suspect that the patient has gum disease or if there are signs of inflammation, bleeding, or infections in the gums. A periodontist specializes in the treatment of gum diseases and can provide more specialized care and treatment options. It is important to follow through with the recommendation to prevent further complications and maintain good oral health.

Who is better for dental implants, oral surgeon or periodontist?

The choice between an oral surgeon and a periodontist for dental implants involves several factors, including case complexity, patient health, and practitioner expertise for surgery and aesthetics (implants). To make an informed decision, consult with both specialists and consider their recommendations along with personal preferences. I also recommend you review their online case studies and reviews. Crucially, ensure the chosen practitioner is licensed and experienced in dental implant procedures.
