Halitosis, or bad breath, is a term 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, and is estimated to be the third-most-frequent reason for seeking dental aid, following tooth decay and periodontal disease. There is no proven effective treatment for bad breath. However, some of the most common bad breath treatments include gently cleaning the tongue service, eating healthy breakfast, chewing gum, gurgling with effective mouthwashes, and maintaining proper hygiene.
