I wake up with a severly dry mouth everyday and believe it to be oral thrush multiplying each night in my mouth. I have tried all the oil pulling with no success and I take coconut oil which I allow to melt in my mouth before swallowing but so far this has not produced any beneficial results.
Last night from a suggestion I saw on another post just before bedtime I cleaned my teeth then gargled some coconut milk kefir and swallowed it, DID NOT clean my teeth again before sleeping and woke up this morning with a huge improvement as to the dryness of my mouth. Its only been one night and I am not saying I have it cracked but I am optimistic that this might help.
Good luck on your efforts
