Bad Breath
Bad breath is a common problem affecting about 1 in 4 people on a regular basis.
Causes
The most common cause of bad breath is poor oral hygiene. Bacteria can build up in the mouth which breaks down pieces of food in the mouth releasing an unpleasant-smelling gas.
Food and drink – Eating strongly flavoured foods – such as garlic, onions, and spices – is likely to make your breath smell. Strong-smelling drinks – such as coffee and alcohol– can also cause bad breath. This is usually temporary.
Smoking – Smoking increases your risk of developing gum disease, which is another cause of bad breath. As well as making your breath smell, smoking can also stain your teeth, irritate your gums, and lessen your sense of taste.
Dieting – Very low-calorie diets (VLCDs) cause the body to break down fats producing ketones that can be smelt on the breath.
Medical conditions – Dry mouth (xerostomia) is where there is a lack of saliva, and this can cause bacteria to build up in the mouth causing bad breath.
Gastro-oesophageal reflux disease (GORD) and H. pylori infections of the stomach lining have also been linked to bad breath.
Treatment
As most bad breath is caused by poor oral hygiene, the most effective treatment is usually improving your dental hygiene:
