BAD BREATH – halitosis – is the third most frequent reason people seek dental treatment, behind tooth decay and gum disease.
Halitosis is most commonly transient, such as when the breath is affected by certain foods, alcohol or smoking.
However, in a small number of cases, halitosis can be persistent and chronic, and may be a consequence of more severe systemic complications.
In 90 per cent of cases, the source of halitosis is located in the oral cavity, primarily due to the tongue.
The posterior part of the tongue has numerous crypts which house a large proportion of bacteria where they lay largely undisturbed, and thrive on food deposits, dead cells and postnasal Dr.ip.
