some time ago, i got rid of plaque from my teeth, n i was ok. suddenly, about 6 months ago, i woke up and my breath was terrible, i brushed n brushed, it only took a while for the bad breath n slimy tongue to return, i have tried different toothpastes, no improvement. recently, when i brush too hard, trying to get rid of the slimy surface, my tongue bleeds, and after about an hour the bad breath and slimy tonge returns and i notice my tongue looks somehow whitish towards the inner parts down the throat, i have contacted some experts, some say it's oral thrush caused by yeast from alcohol or bread, one said it is due to bad nutrition, but i'll really like to know the most likely causes so i can abstain and the cure to this embarrassing problem.
thank you
