Dental Health Risks

Managing Diabetes

Treatment of periodontal disease may lower blood sugar levels in Type 2 diabetes.1

With such a dramatic increase in the number of people with diabetes, taking care of oral health has become an even more important part of managing overall health. In fact, periodontal disease is often considered a complication of diabetes.2 Diabetes is a disease that affects the entire body – even the mouth. That's why good oral care at home, a well-balanced diet and regular dental checkups are important to a healthy body and a healthy mouth.

Periodontal disease and blood sugar levels

Periodontal disease, also known as gum disease, is a chronic bacterial infection that causes inflammation which affects the gums and bone supporting the teeth. Research has suggested patients with diabetes, especially those with uncontrolled blood sugar levels, are more likely to develop advanced periodontal disease and lose teeth.3 Routine maintenance to treat periodontal disease may also contribute to a significant change in blood sugar control for people with Type 2 diabetes, lowering the risk of more serious health issues.

In order to actively assist in managing blood sugar levels, it is important to have a well-balanced diet, practice home care and see your dentist for regular checkups. Be sure to also update your dentist on the status of your diabetes.

Warning signs of periodontal disease

The good news is that early-stage periodontal disease is reversible. Patients with diabetes should have more frequent visits to dental professionals for cleanings and periodic checkups. Since there are varying stages of periodontal diseases that can affect people of all ages, it is important to watch for these early signs:

  • Red and swollen gums
  • Bleeding gums while brushing or flossing
  • Loose or separating teeth
  • Persistent bad breath

Prevention is easy

An estimated 47 percent of U.S. adults aged 30 or older have some form of periodontal disease, and that number climbs to 70 percent for adults aged 65 and above.4 Periodontal diseases range from simple gum inflammation to a more serious condition that impacts the soft tissue and bone supporting the teeth. In the worst cases, teeth are lost. Periodontal disease is preventable with a good daily oral routine, but keep in mind that some people are more prone to periodontal disease. Examples include smokers, diabetics, and people taking certain kinds of medications.

It is important for your dental health to let your dentist know if you have been diagnosed with diabetes and if the disease is under control. Even if you don't notice symptoms, you may still have periodontal disease. Only you and your dentist can determine what is right for you. Check your plan benefits for coverage information.
