What is diabetes and periodontal disease?

People with diabetes have a higher risk of developing periodontal disease, also called gum disease. This condition is an infection of the gums and tissues that support the teeth. When blood sugar levels stay high for long periods, the body may have a harder time fighting bacteria and healing infections.

Gum disease can start as mild irritation and swelling of the gums, but without treatment it may lead to damage of the bone and tissue around the teeth. In some cases, teeth can loosen or fall out.

Several factors can raise the risk of gum disease, including:

• Poorly controlled diabetes
• Smoking or tobacco use
• Inconsistent brushing and flossing
• Plaque and tartar buildup
• Dry mouth
• Weakened immune function

People with diabetes may also experience other oral health concerns such as dry mouth, mouth sores, or oral yeast infections like thrush.

Symptoms

Diabetes and gum disease are closely connected. High blood sugar can make it easier for bacteria to grow in the mouth, increasing the risk of infection and inflammation.

Common symptoms may include:

• Red or swollen gums
• Bleeding when brushing or flossing
• Tender gums
• Bad breath that does not go away
• Gums pulling away from the teeth
• Loose teeth
• Changes in the way teeth fit together
• Pus around the gums or teeth

How is it diagnosed?

A dentist or healthcare provider can check for gum disease during a dental exam. They will look for signs of swelling, bleeding, gum recession, and plaque buildup.

Your provider may also measure the spaces between the gums and teeth, called pockets, to see how advanced the disease is. Dental X-rays may be used to look for bone loss around the teeth.

Regular dental visits are especially important for people living with diabetes because early treatment can help prevent complications.

How is it treated?

Treatment depends on how severe the gum disease has become. In many cases, early-stage gum disease can improve with professional cleanings and better daily oral care.

Common treatments include:

• Professional dental cleanings
• Deep cleaning procedures such as scaling and root planing
• Improved brushing and flossing habits
• Antibacterial mouth rinses or medications
• Better blood sugar management
• Quitting smoking

Advanced gum disease may require additional procedures to repair damaged tissue or bone. Some people may need periodontal surgery, gum grafts, or tooth replacement options such as dental implants.

Managing diabetes is an important part of recovery. Keeping blood sugar levels within a healthy range may help reduce inflammation and support healing.
