Halitosis 口臭

Halitosis, or most commonly bad breath are terms used to describe noticeably unpleasant odors exhaled in breathing – whether the smell is from an oral source due to bacteria or otherwise. Halitosis has a significant impact – personally and socially – on those who suffer from it or believe they do (halitophobia), and is estimated to be the third most frequent reason for seeking dental aid, following tooth decay and periodontal disease.
