For the longest while I have been battling bad breast. I keep having white stuff on the back of my tongue. I try to brush them off but they keep coming back or they don't disappear at all. I try listereine but the white stuff keep reappearing, I even try buying extra hard toothbrush to brush away the white stuff but with no luck. It is getting over bearing because I can't communicate with persons the way I would like to do especially with my boyfriend. When I am around him I try not to talk a lot or I will only speak when I am not so close to him. I don't know what else to do. Thanks for any advise in advnce.

Try changing your toothpaste. I use Kiss My Face whitening toothpaste. Stop using Listerine. Cut back on sugar intake. You could have a candidia (yeast) build up in your system as well.

Usually the smell comes from diet/habits. Don't smoke, stay away from coffee, drink plenty of water, eat regular healthy meals, and yes, brush your tongue, teeth and FLOSS! Smelly bacteria can hide in gum pockets so flossing, brushing, and visiting the hygienist once or twice a year can help.
