Bad breath, or halitosis, develops for a lot of reasons: from food getting trapped in pockets in the tonsils, from the stomach, and from the tongue--where the stench from bacteria buildup can clear a room--as well as food getting stuck in braces.
One good way to handle bad breath: a tongue scraper, which removes bacteria and takes some of the stink away. You need only about ten seconds. Just take the scraper and run it over your tongue. If your breath is just relentlessly offensive, talk to your dentist, who might even prescribe a few days of antibiotics. Your friends (and dates) will thank you.
