Bad breath is a common problem that can cause significant psychological distress. There are a number of potential causes and treatments available.
What causes bad breath?
There are a number of things that can cause bad breath. It’s usually the result of poor oral hygiene. If bacteria build up in your mouth, the toxins produced can cause your breath to smell.
Bacteria break down pieces of food in the mouth and may release an unpleasant-smelling gas. Any food trapped on your teeth – particularly between them – is broken down by bacteria, which may cause bad breath.
Persistent bad breath can sometimes be a sign of gum disease. Eating strongly flavored foods, such as onions and garlic, can also cause your breath to smell, as can smoking and drinking alcohol.
