Far from being a laughing matter, bad breath can be psychologically devastating. Talking to someone is one thing, kissing and being intimate is another. There's no greater passion killer than bad breath.
Halitosis (bad breath) is a common condition caused by sulphur-producing bacteria that live within the surface of the tongue, teeth, gums and in the throat.
The treatment for halitosis will depend on the underlying cause. Smoking, dry mouth, dental infections and nasal or sinus infections can cause bad breath.
