The link between periodontal disease and arthritis

 They are now connecting the dots.  It was known there was a connection, but which came first?

"For many years, there had been suggestions that the oral bacteria causing periodontal disease might contribute to rheumatoid arthritis. For instance, past studies have found that periodontal disease occurs even more often in people with rheumatoid arthritis. People with both conditions also tend to have more severe arthritic symptoms that can be more stubbornly resistant to treatment.

What’s been missing is the precise underlying mechanisms to confirm the connection. To help connect the dots, a research team, which included Dana Orange, Rockefeller University, New York, NY, and William Robinson, Stanford University, Stanford, CA, decided to look closer."

I had gum surgery for periodontal disease about 45 years ago.  I think I also had surgery for a frenectomy at the same time (removal of labial frenulum between front teeth).  Very painful.  Don't let them tell you it's no big deal. Anyway, until recently I've had no pain in my fingers.  Some in left hand now--don't know if it's arthritis or just old age.

Makes me want to leave the computer an floss.
