Post nasal drip, can your breath smell better after you take care of that?

I think I have halitosis, I brush and have good teeth, I go to the dentist he says my teeth are fine. since they wearing the mask they probably couldn't smell my breath. However I think I have it don't know why just do. I also brush my tongue and use a very good mouthwash. calledhttp://www.biotene.com/products/mouthwash.aspx and I also dental floss. Look my aunt told me her daughter breath stinks cause she have post nasal drip. I have post nasal drip real bad sinusis. but my aunt told me I don't have the smell like her daughter. Im just curious.

Most bad breath comes from bacteria on the top of the tongue. Various mints, gum and mouthwashes will cover up bad breath for a short time. However, if you want long term (up to 12 hours) cure for bad breath you must clean your tongue and get rid of the cause of bad breath. I use OraBrush tongue cleaner because it is both a brush and a scraper. Works really well. My wife tells me I have kissing sweet breath.
