Poor oral hygiene is the main cause for bad breath. Bacteria feed on the sugars present in the food. When food settles between or on your teeth, as well as your tongue and gums, it emits gases which have an unpleasant odour. These bacteria are also lead to gum diseases and tooth decay.
Brushing your teeth regularly and cleaning your tongue properly can help control bad breath. It is also important to have a balanced diet, and an improved metabolism to avoid bad breath. Health overall is linked with oral hygiene. Regular dental check-ups will ensure all your dental problems are treated in time.
