If your knees are going bad, the problem may have started in your mouth, Men's Health reports.
A study from the Journal of Rheumatology found bacteria related to gum disease in the hips and knees of people suffering with rheumatoid arthritis.
When it comes to how it got there, researchers said that bad gum hygiene can cause bacteria in your mouth to get carried to your joints through your blood.
The bacteria will cause pain and wear down the joints.
Thankfully, gum disease is reversible and preventable.
