Chemo and dental issues

Hello

I would appreciate some information on chemo and dental issues please

I am currently awating Oncotype results to know if I need chemo. I had a LWE 5 weeks ago and will be having radiotherapy and chemo depending on results.

I came across a post on the chat from earlier this year,  advising some one to get any dental work sorted asap before chemo. Does anyone have more information on this, i delayed dental work just before my surgery as i just wanted to focus on getting the more urgent stuff sorted out?

many thanks
