The American Dental Association says bad breath can be caused by many things. What we eat also affects the we you exhale. Certain foods, such as garlic and onions, contribute to bad breath. Once the food is absorbed into the bloodstream, it is transferred to the lungs, where it is expelled. Brushing, flossing and mouthwash will only mask the odor temporarily.
Odors continue until the body eliminates the food.
Dieters may develop unpleasant breath from infrequent eating. Maintaining good oral hygiene, eliminating gum disease and scheduling regular professional cleanings are essential to reducing bad breath. Brush twice a day with fluoride toothpaste to remove any food debris and plaque. Brush your tongue, too. Once a day, use floss to clean between teeth.
