Chronic bad breath, also known as halitosis, is caused in most cases by a bacterial source in the airway and whilst it may be hard to know that your own breath is malodourous, it is unpleasant for those around us.   Unlike ‘morning breath’ or a strong smell that lingers after eating food, halitosis remains for an extended period of time. Halitosis is a problem that mints, mouthwash or a tooth brushing can’t solve. About 2.4% of the adult population suffers from halitosis and can be a sign of poor oral health or of other diseases.

The causes of halitosis include:

• Dental factors – such as periodontitis (infection around the teeth) or poor oral hygiene. Cavities and deeper pockets from gum disease give sulfur-producing bacteria extra places to live in your mouth that are difficult to clear out with brushing or cleaning between your teeth. Dentures that aren’t cleaned regularly or don’t fit properly can harbor odour-causing bacteria and food particles.
• Smoking and tobacco – Not only does tobacco leave its own odour, it can also dry out your mouth, increasing your risk of gum disease and starves the mouth of oxygen.
• Dry mouth – Saliva helps cleanse your mouth, removing particles that cause bad odors and provides enzymes that help prevent cavities and infection. Several conditions, alcohol, stress and even medications can cause dry mouth contributing to bad breath due to reduced production of saliva.
• Medications –Some medications, as mentioned above can cause dry mouth and bad breath. However, other medications can be broken down in the body and release chemicals that can be carried on your breath.
