What causes bad breath?

Bad breath (scienfic word: Halitosis) can be caused by factors linked to the mouth and teeth (intra-oral) or due to health issues arising from the lungs, digestive system or hormonal disturbances (extra-oral).

The most common causes of bad breath are intra-oral. The build up of bacteria in the mouth, associated with poor oral hygiene, is one of the main causes. Bacteria grow on plaque (food debris) which builds up around teeth, under the gum margins and tongue surface, hence the need for thorough brushing, flossing and regular professional cleans. More severe cases of bad breath can be attributed to established gum disease as a result of poor oral hygiene and neglect over an extended period of time. The types of bacteria in the oral cavity evolve over time if the plaque level keeps growing and this  can lead to more virulent bacteria that cause gum disease and bad breath. 

Large cavities in a tooth and infected teeth are also breeding grounds to bacteria that contribute to bad breath. The wearing of appliances such as braces and dentures can also make oral hygiene more difficult, increasing the level of plaque bacteria in the mouth that contribute to bad breath.
