Hi- my husband is two years post treatment and says that he still felt himself struggling with dry mouth about a year after treatment. Things have improved a lot. Recently, the dentist asked him how he was doing with such a dry mouth and said he didn't feel like his mouth was at all dry.
Hang in there, it will get better. I know the first year especially John was really impatient to see improvement but now we're so grateful that he can eat most things.
all the best
Mary
