Why do I have bad breath?
Oct 20th, 2008 by Dr. Kourosh Maddahi DDS
Halitosis is the medical term used to describe noticeably unpleasant odors that are exhaled during the breathing process. In some cases, bad breath is mostly prominent while talking.
Most bad breath problems begin in the mouth, and are a result of poor dental hygiene. Persistent bad odor from the mouth is indicative of the presence of bacteria that coat teeth and gums.
