Bad Breath - Prevention

Self-care

Try the following steps to improve or prevent bad breath:

• Brush your teeth after you eat. Keep a toothbrush at work to brush after eating.
• Floss at least once a day. Proper flossing removes food particles and plaque from between your teeth.
• Brush your tongue. Giving your tongue a good brushing removes dead cells, bacteria and food debris. Use a soft-bristled toothbrush and brush your tongue with at least five to 15 strokes. Pay particular attention to the middle third of the tongue, where most of the bacteria tend to collect.
• Clean your dentures well. If you wear a bridge or a partial or complete denture, clean it thoroughly at least once a day or as directed by your dentist.
• Drink plenty of water. To keep your mouth moist, be sure to consume plenty of water — not coffee, soft drinks or alcohol. Chewing gum (preferably sugarless) or sucking on candy (preferably sugarless) also stimulates saliva, washing away food particles and bacteria. If you have chronic dry mouth, your dentist or doctor may additionally prescribe an artificial saliva preparation or an oral medication that stimulates the flow of saliva.
• Use a fairly new toothbrush. Change your toothbrush every three to four months, and choose a soft-bristled toothbrush.
• Schedule regular dental checkups. At least twice a year, see your dentist to have your teeth or dentures examined and cleaned.

You can teach your school-age children to brush and floss their teeth regularly and to brush their tongues to prevent bad breath. However, don't give children mouthwash to use, because many mouthwash products contain alcohol and can pose a risk for children if swallowed.
