"Over the last 10 years, tens of millions of people have taken Fosamax believing it would prevent bone deterioration. The drug seemed safe enough at first but in recent years it has been linked to a serious disease that causes death to the bone in the jaw called osteonecrosis of the jaw (ONJ). The disease is an extremely serious condition and symptoms include, but are not limited to:
Pain, swelling, or infection of the gums
Loosening of teeth
Poor healing of the gums
Numbness or the feeling of heaviness in the jaw
Partial or complete loss of the jaw bone"
