Bad breath - Halitosis

Very low urgency
Common-

Commonly referred to as bad breath. It affects 25% of the population and is more common in adults over the age of 50.

It is generally caused by bacteria and is aggravated by poor dental hygiene, alcoholism, consumption of certain foods, coffee, smoking and tooth decay.

It is characterized by bad breath that is difficult for the sufferer to recognize.

It is diagnosed by a clinical interview and a detailed examination of the mouth and nose. A throat culture may be performed if the person experiences pain or mouth ulcers.

To treat the condition, it is recommended that tobacco, alcohol, coffee, and strong tasting and smelling foods be avoided. Drinking plenty of water, brushing teeth, and cleaning the back of the tongue are recommended.
