Halitosis (bad breath) is mostly caused by sulphur-producing bacteria that normally live on the surface of the tongue and in the throat. Sometimes, these bacteria start to break down proteins at a very high rate and odorous volatile sulphur compounds (VSC) are released from the back of the tongue and throat. Halitosis is not infectious. About 2.4% of the adult population suffers from bad breath. Causes of halitosis Apart from the sulphur-producing bacteria that colonise the back of the tongue, the other major causes of halitosis are: Dental factors – such as periodontitis (infection around the teeth) or poor oral hygiene Dry mouth – caused by medicines, alcohol, stress or a medical condition Smoking – which starves the mouth of oxygen. Less common causes of halitosis include: Acid and bile reflux from the stomach Post-nasal discharge – for example, due to chronic sinusitis Kidney failure, various carcinomas, metabolic dysfunctions, and biochemical disorders, together account for only a very small percentage of halitosis suffers Foods - such as onions, garlic or cauliflower, which induce certain odours. However, these effects are only short-lived. >>> Relative article: Swelling gum Symptoms of halitosis The features of halitosis can include: A white coating on the tongue especially at the back of the tongue Dry mouth Build up around teeth Post-nasal drip, or mucous Morning bad breath and a burning tongue Thick saliva and a constant need to clear your throat Constant sour, bitter metallic taste.

A variety of tongue brushes and scrapers have been produced in recent years. The tongue should be brushed in a gentle but thorough manner, from the back towards the front of the tongue, keeping in mind that the hardest to reach back portion smells the worst. People with chronic sinusitis may find the regular use of a saline nasal spray helpful. A course of an antibiotic, effective against anaerobic bacteria (such as metronidazole, to reduce the overgrowth of sulphur-producing bacteria), may also help.
