Yesterday, the Biotene mouthwash started burning too much to use. Rinsing with 2 cups water with 1/2 teaspoon of baking soda seemed to help calm it.

The Biotene toothpaste is doing okay, though the toothbrush is starting to feel like mild sandpaper. My social worker also recommended brushing with devices looking like "sponges on coffee stirrers". For some reason, I thought I read about it here too. Coincidentally, yet another advisor recommended them yesterday and emailed me:

Sponge Swabs:
Toothettes by Sage Products, Inc. 1.800.323.2220 manufactures the toothette.
You can goto their site and click on Clinical Products and Oral care...www.sageproducts.com

I hope this helps someone else, too! I've been recommended to a local dentist specializing on radiation/chemo patients. Hopefully she'll have more recommendations.

Thanks again for everyone's advice!
