Causes

Like other types of body odor many forms of halitosis are the handiwork of bacteria. When the germs that live in the mouth break down food particles and other debris, they often foul the air with highly pungent chemicals.

Treatment

Brushing, flossing and seeing your dentist regularly may reduce bad breath. Some dental hygienists recommend brushing your tongue, since it traps large amounts of bacteria. In addition to good oral hygiene, regular meals (especially a good breakfast) can help keep your mouth moist and fresh. Avoiding cigarettes should be a top priority for anyone who cares about breath odor. And, of course, it's wise to go easy on the garlic and onions before a big date. If you have coffee breath, you might want to cut back on coffee, too.
