Oral Malodour / Foetor / Bad Breath / Halitosis  

Oral malodor (halitosis) is a problem of all ages.  

The most common cause of the oral malodor is the poor oral hygiene. Due to poor oral hygiene, a large number of bacteria belonging to different species make their home in the mouth. They survive on the food particles entangled in between the teeth and as a by-product, produce different substances like Sulphides, Mercaptans and Amines in gas form. These gases are perceived as bad breath by other people.  

Few other diseases may also cause bad breath or oral malodor. Sometimes, a person may feel his / her own bad breath even after a thorough examination and investigations with no apparent cause. The psychological evaluation helps in these cases.  

To treat bad breath, one can follow a home care routine. If it is not going away, contact your dentist or a doctor, because bad breath is also caused by the diseases mentioned below.
