If you live with diabetes, your mouth deserves extra attention. Diabetes and oral health are closely connected: high blood sugar makes gum disease more likely, and gum disease can make blood sugar harder to control. Understanding this two-way relationship helps you protect both your smile and your overall health.
How diabetes affects your mouth
- Gum disease: People with diabetes are at higher risk of gingivitis and periodontitis, and it can progress faster.
- Dry mouth: High blood sugar and some medications reduce saliva, raising cavity risk.
- Slower healing: Sores and surgical sites may take longer to heal.
- Infections: Fungal infections like thrush are more common.
- Taste changes: Some people notice altered taste or a burning feeling.
Why gum health affects blood sugar
Gum disease is a chronic infection that causes inflammation throughout the body. Research suggests that treating gum disease may help improve blood sugar control in some people with diabetes. Caring for your gums is part of caring for your diabetes.
Warning signs to watch for
- Red, swollen, or bleeding gums
- Gums pulling away from teeth
- Persistent bad breath
- Loose teeth or changes in your bite
- Dry mouth or mouth sores that do not heal
