Saliva glands improvements?

Yes for me improvement over four years with the most in the first two. 

Thank you so much for replying so quickly!

You’re very welcome. You will get steps back all the way along the journey nit just at the beginning. Don’t despair, things do move along. 

2+ years since chemoradiotherapy finished, my saliva glands have improved but I still have days when they seem to have stubborn moments, just have to keep them hydrated or chew sugar free gum, Lidl and ALDI brands are very good, contain xylitol which stimulates the saliva glands. For night time dry mouth? I use Biotene gel to keep things right.
