Bad breath (halitosis) is an unpleasant condition that can be cause for embarrassment. If you don't brush and floss daily, particles of food remain in the mouth, collecting bacteria, which can cause bad breath. Food that collects between the teeth, on the tongue and around the gums can rot, leaving an unpleasant odor. Although bad breath is not usually serious, it can be an indicator of a medical disorder, such as a local infection in the respiratory tract, chronic sinusitis, postnasal drip, chronic bronchitis, diabetes, gastrointestinal disturbance, liver or kidney ailment.
If you think you have constant bad breath because of acid reflux, keep a log of the foods you eat and make a list of medications you take. Maintaining good oral health is essential to reducing bad breath. Schedule regular dental visits for a professional cleaning and checkup.
