I've had bad breath & red spots at the back of my tongue that when i touch them with my finger they smell awful. the spots aren't painful. what is this? & what can i do for it ?

Halitosis: An unpleasant odor of the breath. It can be caused by a number of factors, including cavities, periodontal problems, diet, and acid reflux. All of these conditions need to be diagnosed by a local dentist and physician who can actually see you and determine the cause of your bad breath after taking a full medical hx. Once the cause is determined, then treatment can be rendered.
