Almost out of the woods! Seeking advice re teeth cleaning.

I’m 14 weeks post Radiotherapy, had an MRI scan a couple of weeks ago, they called me to say it looked like I had had a complete response to the treatment, but they want to do a pet scan to be sure. So I’m not quite cracking open the bubbly yet (not that I can drink it anyway, it dries my mouth out like the Gobi desert the minute I put any alcohol in it!).

I’m just seeking a little advice on oral hygiene. I was told to brush my teeth 3 to 4 times a day. I brush before breakfast, and do a very light brush afterwards, then brush after lunch and after dinner. Trouble is, I’m still losing weight because I’m not eating anything in between meals, solely because I’m a bit over the top about being careful about oral hygiene, I want to keep my mouth clean but don’t want to over-brush. I just wondered what other people do, do you eat in between meals and if so do you brush afterwards, or just use mouthwash? (I do use interdentals before brushing and after eating as well). I’m a bit paranoid about getting ORN, even though I know it’s rare!
