i have a white spot on my tongue and for weeks i have this slimey substance on my teeth and gums that won't go away - i have changed tooth paste, and changed mouth wash, tried salt water, tried peroxide, & yes i floss and brush 3 times a day trying to get rid of this. when i wake up in the morning i can take my fingers and just globs of white junk i wipe out of my mouth. I went to my doctor and he said it was not thrush. i do not know what to do?? please help
