Can Gum Disease Affect Your Health Beyond Your Mouth?

Researchers have found that people with gum disease are more likely to also have certain general health conditions. That is an association. It does not show that the gum disease caused the other condition, because shared risk factors such as smoking, age and poor diet raise the chance of both.

So the careful position is that gum disease is a marker and possibly a contributor, not a proven cause of these conditions. It is also not a reason to panic. Treating gum disease is worthwhile for the teeth first, and the general health picture is a secondary reason.

The relationship with diabetes runs in both directions. High blood sugar makes gum disease more likely and faster, and the inflammation from gum disease can make blood sugar harder to control. Studies suggest that treating gum disease can modestly improve glycaemic control.

If you have diabetes, tell your dentist and expect closer follow-up. We cover appointments, healing and implants in dental treatment with diabetes. Unexplained rapid gum disease can occasionally be a first sign of undiagnosed diabetes, so it is worth getting a blood test if that fits you.

People with gum disease show higher rates of heart and blood vessel disease. The proposed explanations are shared inflammation and shared risk factors, and large reviews have not shown that treating gums prevents heart attacks. Do not stop any heart medication or advice from your doctor because of your gums.

In pregnancy, gum inflammation is more common because of hormonal changes, and some studies link severe gum disease with preterm birth and low birth weight. The evidence is mixed, and treating gums in pregnancy is considered safe and worthwhile. See dental treatment during pregnancy.

Other associations, including with lung infections in people who cannot clean their mouth, kidney disease and rheumatoid arthritis, are under study and less certain.

On its own, gum disease is not usually fatal. What it does is destroy the bone and gum that hold teeth, and untreated it is a major reason adults lose teeth.

The serious risk is a spreading infection from a dental abscess. Seek care the same day for facial swelling that is spreading, fever, or a severe throbbing pain, and go to a hospital emergency if swallowing or breathing is affected.

Beyond that, the honest answer is that gum disease may add to the load on the body in people who are already unwell, which is a reason to treat it and not a reason to fear it.

The practical steps are the same whatever the link: have your gums measured, treat any pockets, and keep cleaning between your teeth daily. Our gum treatment page sets out the process.

Tell your dentist about diabetes, heart conditions, blood thinners or pregnancy, as these affect planning. Tell your doctor about your gum disease too. Quitting tobacco helps both your gums and your general health.
