Every time I go for a cleaning the Dentist finds something new...as for the eating...someone here suggested adding a little soluble fibre to my beverage at meal time...made swallowing a lot easier. I also have a little choclate milk with a meal too...it is also thicker and easier to get down.
My saliva is back about 20% or so, and I live with a water bottle in my hand so as to avoid dry mouth.
Keep plugging away, it seems to get a little better with time
