While I'm not a dentist I've done this in the past and it does help.
My tongue doesn't really smell that bad.
If a tongue does stink it is a result of something going on elsewhere. Somebody's tongue doesn't just stink. I had a impacted wisdom teeth in the back of my jaw that made my tongue stink pretty bad. Once I removed that wisdom tooth the odour on my tongue decreased alot.
