We are all familiar with how the consumption of certain foods such as garlic and onions can affect our breath. This occurs because these foods are absorbed into our bloodstream, where they are transferred to our lungs and exhaled. Fortunately, bad breath caused by the foods we eat is only temporary.
The truth is, most breath odor comes from food particles trapped in our mouths. When food remains in the mouth, it becomes a breeding ground for the bacteria that can cause bad breath. Other causes can include poor oral health, improper cleaning of dentures, periodontal disease as well as smoking & tobacco products. Bad breath can also be sign of an underlying medical condition of the stomach, lungs and bloodstream.
