Causes of Bad Breath
Bad breath is an indicator of poor oral health care practices and may lead to development of oral problems later on in life. Foul breath could be an indicator of decaying teeth, poor condition of gums, existence of plaque in the teeth etc.
Bad breath may occur because of the bacterial action in the mouth or because of consumption of certain foods that tend to leave a stale taste in the mouth. For example, after meals are consumed, if a person doesn’t rinse his/her mouth adequately, plaque gets settled on the teeth and then bacteria start the work of decomposing the food particles and plaque settled on the teeth. This leads to emanation of peculiar odour.
Rising the mouth with water, swishing it thoroughly so that it reaches all the corners of the mouth and flushes out the food particles will prevent the stale smell that may persist after the food has been eaten.
Eating certain items also lead to lingering smell in the mouth. For example, if you eat garlic or onions, the flavor, fragrance remains in the mouth for a long time and can contribute to foul odour. Similarly, foul odour may emanate on consumption of alcoholic drinks, liquor, and smoking cigarettes. Chewing on beetle leaves also tends to leave a peculiar smell in the mouth. Tobacco consumption can have a similar impact.
Sticky items like milk based sweets, chocolates, peppermint also get settled on the tooth gaps and slowly decay. This will also cause a persistent odd taste in the mouth. Sometimes non vegetarian foods could also be a source of foul breath. For example, after eating omelet, chicken or beef you may have a lingering stale like taste in the mouth.
Not brushing the teeth can be a strong reason for bad breath. Not brushing the teeth in the morning leaves a bitter foul taste in the mouth and it may remain throughout the day.
You may face bad breath even after drinking a cup of strong coffee. Not rinsing your mouth after eating/drinking anything tends to leave the taste in the mouth, and combined by bacterial action foul odour may emanate.

Nice article with some value points. Dont forget that cleaning your tongue is what will remove the bacteria from the back of the tongue (this is where most bad breath smells come from.)
