For the most part
As someone who has been consulted on two cases of osteonecrosis
and legal issues related to lawsuits against novartis, i also respectfully disagree with dr. Twynham. Long term use of bisphosphonates can predispose you to osteonecrosis.
It's unlikely, but you must be informed of the risks. They are low: 1 in 100, 000 but they do happen. Better safe than sorry!
