When you are brushing your teeth, also brush your tongue. The tongue is covered with thousands of tiny hairs that can trap bacteria.

Have regular check-ups with your dentist to rule out gum disease and to correct any faulty restorations, overhanging fillings or leaking crowns, all of which can trap food in the mouth.

Chew sugarless gum or suck on sugarless lozenges to increase the flow of saliva.

If your mouth is dry, drink plenty of water.

Try swooshing it around in your mouth for at least twenty seconds to loosen any food particles the bacteria can feed upon.

Avoid breath mints and mouthwashes that contain alcohol. Instead of helping, they can make things worse. They only temporarily cover the smell and tend to dry the mouth, creating a more favorable environment for bacteria.

Snacking on vegetables such as raw celery or carrots can keep plaque from forming.

If you are going to an important meeting or on a big date, avoid foods that can cause bad breath, such as onions and garlic.

Avoid alcohol and caffeine consumption, which can dry the mouth.
