"For me, the picture that emerges is one in which chronic inflammation
caused by poor oral health sets the stage for more serious illness.
(See my earlier post for more info about the connection between inflammation and cancer.)
I think further research will probably turn up some surprising connections between
oral bacteria and cancer, but we don't have to wait for additional research to begin
taking oral hygiene seriously as a potential way to head off cancer and CVD"
