Hi Jay,
Yes, I have dry mouth, but it’s not as bad as it was after treatment or years after that, but I always carry a water bottle with me, so that helps. The dry mouth, and pretty much continious treatments, did a number on my teeth, so I needed all 30 to be surgically extracted about 4 years into my journey, and now I have to wait to get implants or dentures after healing, and then MI. I doubt implants due to all the radiation I had, and already had ORN, Osteoradionecrosis, from radiation and tooth extraction.
impeccable oral care is a must, and use of prescription fluoride treatments, no alcohol mouth rinse, brushing after each meal, and before bed, and regular visits to your dentist after you finish. You may have needed dental clearance before you started rads, and told when to return?
I hope this helps!
