So I guess my tongue is doing all this because when ever I clean my teeth the breath doesnt go away but if I clean my tongue it seems to go away and then comeback very and if I eat something like a biscuit then after like 15 minutes I get a bad breath with the smell of biscuit (if you know what I am talking about) I want it to go away f or ever and never comeback...what do you guys think do I have a infection or what?
