What is the medical term for bad breath?

Halitosis is the medical term for bad breath and is commonly used in both clinical and everyday language. This term specifically refers to an unpleasant odor emanating from the oral cavity, which can be caused by various factors such as poor oral hygiene, certain foods, or underlying health conditions. Understanding this term is important in the field of esthetics, as maintaining oral hygiene can significantly influence overall appearance and social interactions.

Other options relate to different conditions: odorosis generally refers to an unpleasant smell but is not specific to breath; bromhidrosis specifically pertains to body odor, particularly from sweat; and phantomitis is not a recognized medical term and does not relate to any type of odor or breath condition. Thus, halitosis is the precise and widely accepted term for bad breath.
