Answer:
Halitosis
Explanation:
Halitosis, or bad breath, is when a person exhales an unpleasant odor through the mouth. It may indicate some pathology, physiological change or health problem. It is the odor exhaled through the lungs, mouth and nostrils and can be identified by medical diagnosis and, when chronic, properly treated.
However, halitosis is usually a periodontal disease that occurs when plaque is not properly removed from the tooth surface. In addition to plaque retained in the tooth, halitosis may also be retained in the tongue or tonsils, low saliva production, and gum disease.
