Jon:
You can buy all of the Biotene products through www.dentist.com
I would definitely buy the toothpaste and toothbrush. When I was going through treatment, the flavoring of other brands of toothpaste was just too strong for my mouth.

Also, Biotene's soft toothbrush is softer than any you will find in a drugstore, and it's extremely helpful especially when you're mouth starts getting sore.

I used Aquaphor when my neck was first becoming red and sore while going through radiation. Late, I was given a prescription for 1% silver Sulfadiazine Cream for more sever burns.

Hope this helps
