(HealthDayNews) -- Everyone's had a bout with bad breath, but when it becomes chronic, it's time to see your dentist.

Some sources of bad breath include: what you eat; not brushing and flossing daily; tobacco products; or a medical disorder such as a respiratory tract infection, sinusitis, postnasal drip, bronchitis, diabetes, gastrointestinal disturbance, liver or kidney ailment, the American Dental Association (ADA) says.

The ADA says you should brush twice a day with fluoride toothpaste to remove food debris and plaque, remembering to brush your tongue, too. Once a day, use floss to clean between teeth.

If you must constantly use a breath freshener to hide unpleasant mouth odor, see your dentist.
