Evenity has the lowest reported incidents of osteonecrosis. Evenity stays in your system for about 64 days after the last dose.
Forteo is used to promote healing in the jaw. And is used as treatment for osteonecrosis. I would want a prescription for Forteo during this time, and following. It is not commonly used following Evenity. I think that is because they didn't know that the last nine months of Evenity are actually antiresorptive.
Because the last nine are antiresorptive, i wouldn't want to follow Evenity with another antiresorptive especially Prolia (because I consider it a dangerous drug) but even reclast because there isn't sense in following the antiresorptive with an antiresorptive, and because anabolics build better bone.
I would start Forteo or Tymlos now and wait the 64 days for the dental work.
I write this with confidence only because I know that alternative ideas will follow.
