Emily, you may not be doing damage, per se, but you are providing less protection from the dry mouth issues. I would call your dental oncologist and pose the question. If he already said do it every day, you have the answer and don't need to ask. Protect the teeth at all cost. The complications later may or may not happen but at least you wouldn't second guess your decision.

I've been told my teeth are great and no cavities so far in 11 years. I did get to shell out about $20,000 out of pocket to save some after one broke off at the gum. The broken one had serious abfractions but no cavity. Even gingivitis from gum issues won't be fun after rads.
