I am a fan of Zometa. I tend to think that the weakness in my teeth was due to the chemo itself (as does my oncologist) or my Covid infection at the end of January (which was brief and mild, but Covid nonetheless). I have had improvement in my bone density since the start of Zometa, not to mention researchers are beginning to examine the possible tumor suppression properties of bisphosphonates. For me, taking this med is in the category of throwing everything at this that we can (stage IIIc). Dentists become concerned when they actually have to do anything that goes below the gumline (which it sounds like is not the case for you). The best we can do is keep up with check-ups and daily maintenance, not to mention doing what we can to maintain general health and a healthy immune system: best tools and good for everyone. I believe the standard of care these days is 3 years of Zometa, 6 mos. apart. With all our treatment decisions, we take account of the ole risk/benefit chart.
