What Is the Link Between Gum Disease and Rheumatoid Arthritis? The Inflammatory Connection

You have rheumatoid arthritis. Your rheumatologist keeps asking about your gums. The connection between RA and gum disease is inflammation — and it runs both ways. Here is what the science says.

You visit your rheumatologist and they ask about your gums. You wonder why. The connection between rheumatoid arthritis and gum disease is not obvious — but it is real, and understanding it can help you manage both conditions better.


The Common Thread: Inflammation

Both rheumatoid arthritis and gum disease are fundamentally inflammatory conditions. In RA, your immune system attacks the lining of your joints, causing pain, swelling, and stiffness. In gum disease, bacteria trigger inflammation in the tissues surrounding your teeth. The key similarity is chronic, inappropriate inflammation — and research shows the two conditions feed into each other.


What the Research Tells Us

Studies consistently find that people with RA are more likely to have gum disease than the general population — some research suggests up to 50% higher prevalence. Conversely, people with severe gum disease appear to have a higher risk of developing RA. The relationship is bidirectional: inflammation in your mouth can worsen inflammation throughout your body, including in your joints.

One particular bacteria — Aggregatibacter actinomycetemcomitans — has been linked to both conditions. This pathogen disrupts the immune response in a way that may trigger both gum disease and an autoimmune reaction similar to RA.


Why Your Rheumatologist Keeps Asking

Your rheumatologist knows that managing RA is not just about your joints. Systemic inflammation from gum disease can make your arthritis harder to control. Treating gum disease has been shown to reduce joint swelling and pain in some RA patients. Your oral health is part of your overall inflammatory burden.


What You Can Do

Tell your dentist about your RA diagnosis. They can monitor your gum health more closely and tailor your care accordingly. Stay on top of your oral hygiene — brushing, flossing, and regular dental visits matter more when you have an inflammatory condition.

If you have gum disease, treating it may help your RA symptoms. Book a dental appointment to discuss your options.
