Health Advice: Bad Breath





Bad breath is a common problem affecting about 1 in 4 people on a regular basis.


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.


Strong-smelling drinks
  • Consumption of strong-smelling drinks such as coffee and alcohol can cause bad breath. This is usually temporary.


  • Smoking increases your risk of developing gum disease, which is another cause of bad breath. In addition to making your breath smell, smoking can also stain your teeth, irritate your gums and lessen your sense of taste.
  • 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 in the mouth.This can result in bacteria building 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.


As most bad breath is caused by poor oral hygiene, the most effective treatment is usually improving your dental hygiene:

  • Brush your teeth and gums twice a day with fluoride toothpaste.
  • Use a soft toothbrush and replace it every three to four months.
  • Use an anti-odour mouthwash daily eg; CB12.
  • Floss between your teeth daily to remove trapped food.
  • Use a separate toothbrush or a tongue scraper to lightly brush your tongue.
  • Some toothbrushes have a tongue cleaner on the back of the brush head.
  • Attend your dentist for regular check-ups.
