Odor-producing bacteria triggers bad breath or halitosis. When you're not a fan of brushing and flossing regularly, you are more susceptible to this stinking mouth scare. Bacteria gather on the bits of food left in your mouth as well as in between your teeth. It then releases a sulfur compound, which makes your breath smell. If you're fond of garlic and onions, you may want to go easy on it. The oils from these food are carried over to your lungs and then to the mouth. Chain smoking and poor dental habit also contribute to bad breath.
