I have been taking Aggrenox since 2004 with great success. For the last 2 weeks, I have excessive saliva during the day, but not at night when I can experience dry mouth (I'm 80 years old). I find myself drying the corners of my mouth during the day now, which I never ever felt a need to do. I am not getting a cold and consider myself to be in very good health. I don't seem to have any infections. My mouth is kept extremely clean, using floss brushes 2 X day and water irrigation after eating. I do have all my own teeth, but gums are quite receded.
