The important connection between diabetes and oral health

By TRICARE Dental Program

According to the Centers for Disease Control and Prevention, about 12 out of every 100 Americans have diabetes.  However, many people underestimate how important their oral health is in managing their diabetes.

Read on to learn how you can take care of both your diabetes and your oral health at the same time.

Oral health complications and diabetes

Periodontal disease is the inflammation and infection of the gums and the bone that surround and support the teeth. This leads to swollen, bleeding gums, bad breath, and eventually the breakdown of bone and tissues supporting teeth. This may potentially result in tooth loss. According to the CDC, treating gum disease can actually help improve blood sugar.

Other oral complications of diabetes include:

  • Dry mouth (xerostomia): Reduced saliva flow, often from diabetes or medications, increases the risk of tooth decay and oral infections because saliva helps wash away food and neutralize acids.
  • Increased risk of cavities: Dry mouth and higher glucose levels in saliva contribute to more tooth decay. Adults with diabetes are 40% more likely to have untreated cavities.
  • Thrush (oral candidiasis): A weakened immune system makes fungal infections like thrush more common. Thrush appears as white patches in the mouth.
  • Impaired healing: Healing after dental procedures can be slower and more complicated because of the nature of diabetes.

Protecting your smile and your health

To help manage your diabetes, make sure you’re following these important steps.
  • Blood sugar control: Manage your glucose levels through diet, exercise, and medication to reduce your risk of oral health complications like gum disease.
  • Diligent oral hygiene: Brush twice daily with fluoride toothpaste and floss once a day.
  • Regular dental check-ups: Inform your dentist about your diabetes. Regular visits allow for early detection and treatment.
  • Stay hydrated: Drink plenty of water to combat dry mouth. You can also chew sugar-free gum to increase saliva flow.
  • Avoid tobacco: Smoking significantly worsens gum disease, especially with diabetes.
  • Healthy diet: Limit sugary and starchy foods and drinks.
