In the most instances halitosis or bad breath is caused by poor oral hygiene and consequent accumulation of plaque bacteria and development of gum disease. The bacteria produce sulphides which result in bad breath.
Brush your teeth effectively and use floss and interproximal brushes to clean between the teeth. Cleaning the tongue is also necessary as many bacteria are present on the back of the tongue. See your hygienist for advice on tongue cleaners.
Some people worry too much about their breath even though they have little or no mouth odor, while others have bad breath and don’t know it. Because it’s difficult to assess how your own breath smells, ask a close friend or relative to confirm your bad-breath questions..
