Main causes of bad breath

Diseases of the teeth and gums:
Cavities in the teeth.
Gingivitis/Periodontitis.
Plaque/Tartar on the teeth.
Dirt accumulating on the tongue: Bacteria accumulating on the back of the tongue is a major cause of bad breath.

Gastritis: Indigestion or stomach acidity problems.
