If you’re living with diabetes, you already know it affects more than just your blood sugar — it impacts your eyes, feet, nerves, and even your heart. But did you know your oral health is also closely connected to diabetes?
Whether you’ve been recently diagnosed or managing diabetes for years, understanding how it affects your teeth and gums — and vice versa — is key to staying healthy overall.
Here’s what you need to know about the link between diabetes and dental health, and how your dental team can help.
How Diabetes Affects Your Oral Health
When blood sugar levels are high, it can weaken your body’s ability to fight off infections — and that includes infections in your mouth.
The most common dental issues linked to diabetes include:
🦷 Gum Disease (Gingivitis and Periodontitis)
People with diabetes are more prone to gum infections due to poor circulation and a weakened immune response. Gum disease can range from mild inflammation (gingivitis) to advanced bone and tissue loss (periodontitis), which may lead to loose or lost teeth.
🦷 Dry Mouth (Xerostomia)
Diabetes can reduce saliva production, especially if you’re on certain medications. A dry mouth increases your risk of cavities, bad breath, and oral infections like thrush.
🦷 Slow Healing
High blood sugar slows the body’s healing process, meaning dental procedures — like extractions or gum treatments — may take longer to recover from.
🦷 Oral Thrush (Yeast Infection)
Thrush is more common in people with diabetes, especially those who wear dentures or have dry mouth. It appears as white patches or redness on the tongue or inside the cheeks.
🦷 Tooth Decay
When saliva is reduced and blood sugar is high, harmful bacteria thrive. This can lead to an increased risk of cavities, especially near the gumline.
How Poor Oral Health Affects Diabetes
The connection goes both ways.
Untreated gum disease can make it harder to control blood sugar levels, which can worsen diabetes symptoms and increase your risk of complications. Inflammation from gum infections raises blood sugar levels, creating a cycle that’s hard to break without dental care.
Taking care of your mouth supports better diabetes management.
Signs to Watch For If You Have Diabetes
If you notice any of these symptoms, book a dental visit promptly:
- Bleeding or swollen gums
- Persistent bad breath
- Loose teeth
- Dry mouth
- Sore or infected gums
- Burning sensation on the tongue
- White patches inside the mouth (possible thrush)
Oral Care Tips for People with Diabetes
- ✅ Brush twice a day with fluoride toothpaste
- ✅ Floss daily to remove plaque between teeth
- ✅ Stay hydrated to reduce dry mouth
- ✅ Avoid tobacco, which worsens gum disease
- ✅ Eat a balanced diet to help control blood sugar
- ✅ Visit your dentist at least twice a year — or more often if recommended
- ✅ Let your dental team know about your medical history and medications
