Halitosis (bad breath) occurs when the mouth emits a foul odor. This may occur periodically, or it may be a long-term condition, depending on the underlying cause. People are not always aware that they have bad breath because the nerve cells in the nose may become accustomed to the odor.
Depending on the underlying cause, additional symptoms may also be present. For instance, if poor oral hygiene is causing the condition, the teeth may become coated with plaque, the gums may be pale or swollen, and tiny food particles may become trapped in between the teeth. If an infection of the mouth is causing bad breath, the gums may be swollen, red, sore, and/or bleed easily (especially after brushing or flossing).
