The clinical term for bad breath is halitosis.  Bad breath is primarily caused by poor oral hygiene, but can also can be caused by retained food particles or gum disease. Proper brushing including brushing the tongue, cheeks, and the roof of the mouth will remove bacteria and food particles. Flossing removes accumulated bacteria, plaque and food that may be trapped between teeth. Mouth rinses are effective in temporary relief of bad breath. Consult your dentist and/or physician if the condition persists.\n\nIt is important to practice good oral hygiene, such as brushing and flossing your teeth at least twice a day. To alleviate the odor, clean your tongue with your toothbrush or a tongue scraper, a plastic tool that scrapes away bacteria that builds on the tongue. Chewing sugar-free gum also may help control the odor. If you have dentures or a removable appliance, such as a retainer or mouthguard, clean the appliance thoroughly before placing it back in your mouth. Before you use mouth rinses, deodorizing sprays or tablets, talk with your dentist because these products only mask the odor temporarily, and some products work better than others.
