Halitosis,
also called bad breath, unpleasant odor from mouth.
Bad
breath can result from poor dental health habits and may be a sign of other
health problems.
If you
don't brush properly your teeth daily, food particles can remain in your mouth,
which promotes bacterial growth between teeth, around the gums, and on the
tongue. This causes bad breath. May be warning signs of gum (periodontal) disease or dental
cavities.
