CURE MOUTH ODOUR PERMANENTLY

SELF-TREATMENT
Brushing teeth and tongue after eating, flossing at least once a day and replacing toothbrushes regularly may improve bad breath. Avoiding foods known to cause bad breath, such as onions and garlic, may also help.

SEEKING MEDICAL CARE
See a doctor if you
Also develop a fever or nasal discharge with pus
Get mouth sores that can be seen or felt
Still have bad breath after self-treatment
Also experience heartburn or chest pain

OTHER CAUSES.
Diseases, such as some cancers, and conditions such as metabolic disorders, can cause a distinctive breath odour as a result of chemicals they produce. Chronic reflux of stomach acids (gastroesophageal reflux disease, or GERD) can be associated with bad breath. Bad breath in young children can be caused by a foreign body, such as a piece of food, lodged in a nostril.
