Gum disease and diabetes have a two-way relationship. People with diabetes are more likely to develop gum disease, especially when blood sugar is hard to control. At the same time, research suggests that serious gum disease may make it harder to keep blood sugar in a healthy range.
The good news is that caring for your gums and managing your blood sugar can support each other. Here’s what patients with diabetes should know about protecting their smiles.
If you have diabetes and haven’t had your gums checked recently, call Thomas F. Brown, DDS, at (630) 283-1851 to schedule a visit in Naperville.
How Are Gum Disease and Diabetes Connected?
Gum disease is an infection caused by bacteria that build up along and below the gumline. Diabetes can make it harder for your body to fight that infection in a few ways:
- Higher sugar levels in saliva can feed the bacteria that cause plaque.
- Slower healing means irritated gums may take longer to recover.
- Reduced blood flow to the gums can weaken their defenses.
- Dry mouth, which is common with diabetes, leaves less saliva to wash bacteria away.
Together, these factors can allow gum disease to start earlier and move faster.
Can Gum Disease Affect Blood Sugar?
Research suggests it can. Gum disease causes ongoing inflammation in the body. That inflammation may make it harder for your body to use insulin well, which can make blood sugar more difficult to manage.
Some studies have found that treating gum disease may help with blood sugar control for some people with diabetes. Gum care isn’t a replacement for your diabetes treatment plan, but it can be an important part of caring for your overall health.
What Are the Signs of Gum Disease to Watch For?
Gum disease often starts quietly. Watch for these signs:
- Gums that look red, puffy, or swollen
- Bleeding when you brush or floss
- Bad breath that doesn’t go away
- Gums that seem to be pulling away from your teeth
- Teeth that feel loose or are shifting
- Slow healing after small cuts or sores in your mouth
If you notice any of these, schedule an exam soon. The earlier gum disease is found, the easier it is to treat. In fact, early gum disease can often be reversed with a professional cleaning and good home care.
How Can You Protect Your Gums If You Have Diabetes?
A few daily habits make a real difference:
- Keep your blood sugar in your target range. Work with your physician on a plan that fits you.
- Brush twice a day with a soft-bristled toothbrush and fluoride toothpaste.
- Floss every day to clean between teeth and below the gumline.
- Stay hydrated to help with dry mouth.
- Avoid tobacco, which raises the risk of gum disease even further.
- Keep your dental visits. Many patients with diabetes benefit from more frequent cleanings.
What Should You Tell Your Dentist About Your Diabetes?
Let our team know that you have diabetes, even if it’s well controlled. It’s also helpful to share:
- The medications you take, including insulin
- How well your blood sugar has been controlled lately
- Any recent changes to your health or treatment plan
Try to eat normally and take your medications as usual before your appointment, unless your physician tells you otherwise. Morning appointments often work well for patients with diabetes.
How Is Gum Disease Treated for Patients With Diabetes?
Treatment depends on how far gum disease has progressed. Early gum disease may only need a professional cleaning and better home care. For more advanced gum disease, the dentist may recommend a deep cleaning called scaling and root planing, which removes bacteria and tartar from below the gumline.
After treatment, regular periodontal maintenance visits help keep bacteria under control and protect your progress.
