Re dental work, agree with the advice given especially not doing work if you can do it before or after however worth noting that I had no dental problems while on chemo and my dentist said he would not have known if not duly advised before I started chemo. I had A/C and Taxol. No mouth ulcers either. I did swish and spit religiously twice a day - my oncology nurse said 4 times is great but people find it onerous or forget, always doing twice every day was just as good. I'm on Femara which is not good for bone density but the only problem (a deep seated crack) undoubtedly started before I went on Femara, although discovered later. No bone issues with an implant to resolve the problem, just a bit of bleeding but that's because I am on blood thinners!
