I have read of teeth falling out, as well as dental implants becoming 'unincorporated' in the jaw as a result of BRONJ (bisphosphonate related ostenecrosis of the jaw) and a friend on Zometa was told that she should take it for no more than 3 years 'to be safe.' The jawbone doesn't just die, it loses blood supply, ergo the risk of any oral surgeries that leave tissue that needs to heal is that cannot in the absence of blood supply. And infections in open remaining tissue are extremely difficult to treat as there's inadequate blood supply to carry antibiotics to the site.

I have a great prosthodontist (and two dental implants) who's had to decline patients on some of the osteoporosis drugs because of the difficulties. He knows of no others who are willing to treat patients with osteonecrosis of the jaw (which one oncologist whose opinion I read thinks is a misnomer and that the condition 'looks more like osteomyelitis' to him).

Dr. S. told me how difficult it is for BRONJ victims to get help and it's a condition devoutly to be avoided in any way possible in my opinion. And caused me to improve diet and get back to the gym in hopes if keeping osteoporosis far away.
