Really very detailed information is provided. Thanks a lot for sharing this information. I am facing problem with saliva secretion. Earlier I use to eat dry food like bread, pohaa, etc very easily and fast. But it's taking too much time now and also need some liquid item like gravy, rassam. And it's because of lack of saliva. But whenever I am very hungry I can eat anything fast without any difficulty. Actually I have done root canal of all my tooth. And I think I am facing this problem after that treatment. Also I am a flute player. But I hope it's not because of blowing. What's the cure for this? Any medicine available? Any help will be appreciated Thanks in advance.
