"Halitosis or bad breath is an abnormal condition of the breath that changes unpleasantly.
Surveys performed in Brazil reveal that approximately 30% of the population suffers from this problem, which is about 50 million people.
Halitosis is not a disease but can report the occurrence of any disease or health problem. However, it can also be a sign of physiological change. Therefore, it is a sign that something is out of balance in the body and should be identified through a correct diagnosis and treated properly when the problem becomes chronic."
