Dentists in Indiana are concerned about seeing more cases of jaw necrosis (decaying jaw bone) linked to the use of bisphosphonates. Apparently you don't have to have a dental procedure for it to occur.
Some cases of ONJ have appeared after someone using bisphosphonates has had a tooth pulled or some other dental procedure, but other cases have appeared “spontaneously,” according to a recent article in Dental Economics
“As far as the dental profession is concerned, there is a definite link [between ONJ and bisphosphonates] and there is no question about that,” Foulkes said. “Our controversy is how to deal with it.”
