Bad breath affects a large number of adults. Sometimes, it is simply a result of the foods that you choose to eat but not because they are still present in your mouth. Halitosis can be brought on after eating foods like garlic and cabbage. When the food enters your blood, it will eventually transfer to your lungs. The smell of the food will still be present when you exhale. However, bad breath can result from a variety of other causes such as oral disease or infection, dry mouth, poor oral hygiene and tobacco use. Visit your dentist if you experience chronic bad breath but avoid foods known to cause Halitosis.
