If you have diabetes, even your mouth is affected. Regular dental care and managing your blood sugar level go hand in hand to keep both your body and mouth healthy.

Gum Disease and Blood Sugar Levels

Gum disease — also called periodontal disease — is a chronic bacterial infection. It  causes swelling that can hurt the gums and bone supporting teeth. This swelling, or inflammation, can lead to higher blood sugar levels, according to the American Diabetes Association.

Research also shows people with uncontrolled blood sugar levels are more likely to get advanced gum disease and lose teeth. High blood sugar levels in saliva promote the growth of harmful bacteria. This can cause the plaque and tartar buildup that lead to the disease.

For these reasons, diabetes and gum disease are linked. Routine dental care is key. Keeping gums healthy will help prevent gum disease and may help people with Type 2 diabetes control their blood sugar levels.

In addition to dental care, keeping blood sugar levels under control helps lower the risk for gum disease and other serious health issues. Along with diabetes, scientists have found links between gum disease and heart disease, stroke and high-risk pregnancy.

To help manage blood sugar levels, eat a balanced diet, take care of your mouth and see your dentist for regular exams. Be sure to tell your dentist about any changes in your health.

Know the Warning Signs

Gum disease has several warning signs. Watch for:

• Red and swollen gums
• Bleeding while brushing or flossing
• Dry mouth
• Loose or separating teeth
• Bad breath

Talk to your dentist about your risks for gum disease. Together, you can work out a plan to keep your gums healthy.

Pay Attention to Prevention

Taking care of your teeth and gums pays off. It’s easier to avoid getting gum disease than to fix the problems it may cause once you get it.

Use these daily habits to help keep your mouth healthy:

• Brush your teeth at least twice a day 
• Floss your teeth
• Eat healthy foods
• Manage blood sugar levels
• See your dentist twice a year
• Never use tobacco

Remember, diabetes can cause serious problems in your mouth and having gum disease can make your diabetes harder to manage. With commitment and the right care, you can do something about both.
