So glad you are here. You're in the right place for lots of support and practical help! It's been a while since my son was recovering from his radiation treatment, and he did have lots of saliva problems but it was manageable, though and got better slowly depending on how far he was from end of treatment. I'm sure you will hear from others with more direct and recent experience and suggestions. Until you do, have you tried doing a search in the little search box upper right of this page? Just type in "saliva" and it will take you to a thread with lots of helpful comments.
