The bad news? An estimated 40 million people have bad breath [source: American Dental Hygienists' Association]. The good news? Daily oral hygiene practices that include brushing and flossing will help keep your breath fresh, as well as keep your teeth and gums healthy. Dentists recommend brushing your teeth two or three times every day. They also stress the importance of daily flossing. And if you haven't tried it, consider using a tongue scraper: Tongue scrapers help remove all the residue that can hide in the tongue's nooks and crannies, and less residue means you're less likely to be one of those 40 million.
