I started to develop dry mouth in the last year or so. I knew it was from radiation I had received and I started searching for information. Biotene kept popping up, had good reviews so I got the spray, it was okay-not enough power for my symptoms. Got the mouthwash and it that helped tremendously!! Such relief, when buying my 3 bottle of mouthwash I saw the toothpaste and I bought it. My symptoms are gone!!!! Gone!!!! I brush with the biotene 2/day and then rinse with the mouthwash. You would never know I ever had dry mouth so badly I could not eat anything! I absolutely recommended you do the toothpaste and moth wash together!
