Your previous post has website from MYdentist-Mike would be that dentist. Its his website.
Me just a guy who had bad health problems that were cured by cleaning out my jaw
FYI-screws in jaw. You do know how the immune system works-you never really want anything not you in you.
If I were you I would be more concerned with whoever told you root canals are safe or metal screwed into you bone is safe. Many serious doctors and dentist do not think either is safe
