Researchers are studying how gum disease and oral bacteria interact with the immune system in rheumatoid arthritis.
Mouth bacteria matter.
A human study linked oral bacteria entering the blood with immune activity in rheumatoid arthritis. Researchers are investigating how this may contribute to inflammation.
Keep your care connected.
Tell your dentist about your arthritis and medicines. Ask about bleeding gums or hand stiffness that makes brushing and cleaning between your teeth harder.

About the mouth–joint research
Human research has identified links between gum disease, oral bacteria and immune responses in rheumatoid arthritis. A separate 2024 animal study found that a periodontal bacterium worsened arthritis in mice. These findings do not establish that mouth bacteria cause all arthritis or that oral-care products prevent or treat it.

Frequently Asked Questions
Researchers have found links between gum disease, oral bacteria and immune activity in rheumatoid arthritis. The relationship is still being studied. Read the research ↗
No. Joint symptoms have many causes. Rheumatoid arthritis is an autoimmune disease, and findings about it do not apply to every form of arthritis or joint pain.
OneOral provides oral-health care. Its products do not replace arthritis treatment or care from your doctor or rheumatologist. Your dentist can help care for your gums alongside your medical treatment.
No. The optional saliva test looks for selected oral microbes and measures features of your saliva. It does not diagnose arthritis or measure inflammation in your joints. Testing is priced separately.
Tell your dentist about any diagnosed arthritis, the medicines you take, bleeding gums and any hand or jaw stiffness that makes your routine difficult. They can help adapt your oral care.
There are three plans. OneOral is $9.99/month: message a licensed dentist and share photos, get ongoing dentist check-ins, and pay member prices on kits, whitening and gum. Nothing ships automatically on it. OneOral+ is $29.99/month and adds a Treatment Box (CariFree Maintenance Rinse and Gel 1100 toothpaste) every 3 months with free shipping. Power Pack is $44.99/month: the Treatment Box plus whitening, energy gum and breath mints or oral spray. Sales tax is added where it applies.
OneOral renews monthly; cancelling stops the next renewal and access continues until the end of the period you paid for. OneOral+ and Power Pack bill monthly in cycles of 3 payments per box. Cancelling stops the next cycle and its box; the remaining payments for the current cycle are still collected on their normal dates. Full details are in the plan terms.
Start by sending a photo or describing what’s going on. With a membership you can message a licensed dentist about it. OneOral is designed for most adults and complements — never replaces — your regular in-person checkups.
No. OneOral is not insurance and you don’t need any. Each plan is a flat monthly price, plus sales tax where it applies.
On any plan you can message a licensed dentist and share photos. On OneOral+ and Power Pack, your first box ships once your first payment is made. The Treatment Box (and Power Pack’s mints or spray) then ships every 3 months; Power Pack’s whitening and energy gum ship every 6 months. Shipping is free, to US addresses only.
When clinically appropriate and permitted for your situation, a licensed dentist can send a prescription to your local pharmacy for pickup. Prescriptions are not guaranteed. Pharmacy charges may apply; some concerns require in-person dental treatment.
