No one knows how many people suffer from bad breath, but recent research estimates around 20% do. However, we do know that 90% of halitosis originates in the mouth and rarely comes directly from the stomach.

Booking your regular check-up is essential as the mouth has many potential malodour sources. Faulty restorations are a common cause, often leading to a foul taste. Old leaking fillings, poor-fitting crowns, and food impaction sites are breeding grounds for bacteria that cause bad breath.

The most frequently overlooked source is the back of the tongue. This posterior area of the mouth is often neglected during dental hygiene routines at home.

Bacteria found between teeth are also likely to cause bad breath. People who neglect to floss and brush correctly and develop interdental plaque are more likely to develop gum disease, making bad breath a possible sign of gingivitis or periodontal disease.

Dry mouth, a condition in which the salivary glands don't produce enough saliva to keep the mouth moist, can be another cause of bad breath or halitosis. It can be caused by the side effects of some medications, ageing issues, or radiation therapy for cancer.

Many unrelated conditions, such as lung infections, metabolic dysfunctions and biochemical disorders, can result in bad breath, but these account for only a tiny fraction of cases. Bad breath is also considered a diagnostic indication for diabetes.

Strong odours from foods such as garlic, onions, and alcohol are external sources of odour. Some are retained in the mouth, and others enter the bloodstream. They are then slowly released through the skin via breath or sweat.

Although dental floss is a much-disliked part of hygiene, its proper use can significantly decrease bad breath and gum disease. Together with deep tongue cleaning, this should form an integral part of daily oral hygiene, leading to a fresher, healthier breath.

Book an appointment with one of our dentists or oral hygienists at Hout Bay Dental Studio if you struggle to manage halitosis. In most cases, proper dental treatment, effective oral hygiene, and tongue cleaning can effectively prevent bad breath.
