I haven't even started any treatment yet. Haven't even had my surgery yet but OMG the mouth pain. I don't know how you folks in radiotherapy manage.

I have been brushing my teeth by using a couple of drops of lavender or tea tree essential oil on my toothbrush. They are anti bacterial, antifungal, antiseptic and most important of all they are slightly analgesic. Just don't swallow it. I also add a few drops to warm water and use that for mouth wash.

It is so much better feeling than mouth wash or toothpaste right now. It helps some with the deathbreath from not being able to brush well due to the pain.

I use a children's toothbrush too. They are very soft and small enough to reach almost everything without too much pain.
