I have invisalign while on Prolia and I've had no issues except that my teeth seem to be moving more slowly. I have to wear each tray longer than they say. I assume that is due to the bisphosphonates but don't know for sure. I am switching to Reclast next month. My bottom teeth were shifting forward so much that they were really crooked and overlapping which made it hard to keep them clean. They felt that I would be able to reduce the potential of dental problems w/those teeth if we could fix the crowding.
