Managing Gum Health with Diabetes

People with diabetes are more prone to infections—and that includes gum disease. In fact, periodontal disease is often referred to as the sixth complication of diabetes, especially when blood sugar is not well-controlled.

Periodontal disease (also known as gum disease or periodontitis) is a progressive infection that affects the gums and the bone supporting the teeth. If left untreated, it can lead to gum recession, bone loss, and eventually tooth loss.

Diabetes is a chronic condition marked by elevated blood glucose levels. In type 1 diabetes, the body doesn’t produce insulin. In type 2, the body can’t use insulin properly or doesn’t produce enough. Both types can impact overall health and increase the risk of heart disease, stroke—and gum disease.

Why diabetes and gum disease are closely connected

When either condition is poorly managed, it can make the other worse. Here’s how diabetes and periodontal disease are related:

    Higher blood sugar levels
    Advanced gum disease can raise blood sugar, making it harder for people with diabetes to control their glucose levels. At the same time, high blood sugar in the mouth fuels the bacteria that cause gum infections.
    Poor blood flow
    Diabetes can lead to the thickening of blood vessels, making it harder for nutrients to reach the gum tissue and for waste products to be removed. This weakens the gums and increases the risk of infection.
    Smoking
    Tobacco use significantly increases the risk of gum disease. For people with diabetes, the risk is even greater—especially for those over 45. Diabetic smokers are up to 20 times more likely to develop periodontal disease.
    Inadequate oral hygiene
    Without daily brushing and flossing, harmful bacteria feed on the extra sugar in the mouth and quickly build up along and beneath the gumline. This not only worsens oral health but also makes blood sugar control more difficult.

If you have diabetes and are concerned about your gum health, don’t wait. Early intervention can make a big difference in controlling both conditions. Contact our office today to schedule an evaluation.

Diagnosis & treatment

If you have diabetes, seeing your dentist regularly is crucial—at least twice a year. Research shows that even simple, non-surgical periodontal treatments can reduce HbA1c (a key diabetes marker) by up to 20% in just six months.

During your visit, your dentist will:

    Review your medical and family history.
    Take dental X-rays.
    Evaluate the health of your gums and jawbone.

If gum disease is detected, your dentist may collaborate with your physician to manage both conditions effectively.

Treatment options may include

    Deep Cleaning (Scaling and Root Planing)Removes plaque and tartar from above and below the gumline, and smooths the root surfaces to eliminate bacteria.
    Antibiotic TherapyMedication may be applied directly into gum pockets to control infection and support healing.
    Ongoing MaintenanceYour dental team will recommend a personalized at-home oral care routine, along with prescription rinses if needed.
