I have just posted but then I saw your post. I had dry mouth and went to an ENT specialist and she discovered that there was no saliva coming from my 2 main salivary glands situated one in each cheek. There are 3 salivary glands. The 2 main ones are situated one in each cheek and the third one near the back of your throat/neck area I think it is. The salivary gland in the throat/neck area however is still functioning but it is not the main one. Hope this helps you to understand. At least that is how I understood it but talk under correction,
