There is a new study from Australia, published in the Journal of the Canadian Dental Association, that shows the connection between taking bisphosphonate drugs - Fosomax, Boniva and Actonel and jawbone collapse.
Although most doctors believe that the problem is with intravenous drugs given in cases of cancer, it has been proven that oral drugs have the same problems. It is the conjuction of bone drugs plus dental surgery for replacement of teeth or root canals that compounds the problem. Who among us can say when their teeth will need some deep work?
Even if you have only taken the drugs for less than three years there is still a risk. Since the drugs stays in your system for ten years, the risk is also present for ten years.
