I think some of the major concerns about dental work relate not so much to the chemo but to some of the drugs that may be used to prevent osteoporosis if you end up having hormone treatment. I wouldn't want to be having dental surgery in the middle of it just the same.
Ask your oncologist; stick that question on your list so you know for certain what you do, or don't, need to worry about.
It comes as a shock when you think you are heading down be track and you end up getting pushed down another. It would be helpful if surgeons could refrain from giving advice about oncology, oncologists wouldn't speculate about plastic surgery and people didn't tell you stories about friends of friends who have exactly the same disease as you and had different treatment. Tune up your bullshit metre, you may need it.
My best advice is try to keep informed but don't drive yourself mental, figure it if you trust your team, and if you do, let them do their jobs. If you don't, change them. Keep a diary and most of all, be kind to yourself if you can. Take any opportunity to rest. One step at a time. Marg xx
