Gum disease, also called periodontal disease, affects the gums and other tissues that support the teeth. It ranges from gingivitis, which is usually reversible, to periodontitis, which can damage bone and lead to tooth loss.
Gum disease is important to treat, but it is misleading to say that gum disease itself directly “kills” people. The strongest evidence is that periodontal disease is associated with several chronic health conditions and can make some conditions—especially diabetes—harder to manage.
Can Gum Disease Be Dangerous?
Untreated periodontitis can cause significant oral damage, including gum recession, bone loss, loose teeth, pain, and tooth loss. Severe dental infections can occasionally spread beyond the mouth and need urgent treatment, but this is different from saying ordinary gum disease directly causes death.
Gum Disease and Diabetes
The relationship between diabetes and gum disease works in both directions. People with diabetes, especially when blood sugar is poorly controlled, have a higher risk of more severe periodontal disease and slower healing. In turn, gum disease may make blood sugar harder to manage.
Treating gum disease may help blood-sugar control in some people, but dental treatment is not a replacement for diabetes medicines, insulin, nutrition care, or other parts of a diabetes treatment plan.
What About Heart Disease, Stroke, Dementia, Kidney Disease, or Cancer?
Studies have found associations between periodontal disease and several systemic conditions. However, association does not prove that gum disease directly causes heart attacks, stroke, dementia, kidney disease, or cancer. Shared risk factors such as smoking, age, diabetes, inflammation, access to care, and overall health may contribute.
It is reasonable to protect your oral health, but claims that treating gum disease will prevent or cure these diseases go beyond the evidence.
Common Signs of Gum Disease
- Red, swollen, or tender gums
- Gums that bleed easily
- Persistent bad breath
- Gums pulling away from the teeth
- Loose or sensitive teeth
- Pain when chewing
- A change in how the teeth fit together when biting
What Causes Gum Disease?
Dental plaque is the main driver. When plaque is not removed, it can harden into tartar, which requires professional cleaning. Important risk factors include tobacco use, diabetes, poor oral hygiene, older age, genetics, and some medicines or health conditions.
How Is Gum Disease Treated?
Treatment depends on severity. Gingivitis can often improve with effective brushing, interdental cleaning or flossing, and professional cleaning. Periodontitis requires professional dental treatment and may involve scaling and root planing, targeted medicines or rinses, and sometimes surgery.
Do not rely on home remedies such as oil pulling, herbal products, or peroxide rinses as substitutes for dental assessment when gum disease is suspected.
How to Reduce Your Risk
- Brush twice daily with fluoride toothpaste.
- Clean between teeth regularly with floss or another recommended interdental method.
- Do not smoke or use tobacco.
- Attend dental checkups and professional cleanings at the interval recommended for you.
- If you have diabetes, work with your healthcare team to manage blood glucose and tell your dentist that you have diabetes.
When to Seek Prompt Care
See a dentist if you have persistent bleeding gums, swelling, gum recession, loose teeth, pus, significant pain, or persistent bad breath. Seek urgent medical or dental care for rapidly spreading facial swelling, difficulty swallowing or breathing, fever with a serious dental infection, or severe illness.
