Bad breath is also known as oral malodor or halitosis. It is a very common and latterly treatable condition which is seen in case of many adults. There are several common causes of bad breath and if you know about them, you’ll be able to do something about them so that you do not suffer from this problem.

Poor oral health

If you have poor oral hygiene, you’re likely to suffer from bad breath. If you do not clean your teeth and your whole mouth regularly, you are sure to suffer from this problem. When you do not clean your mouth and teeth every day and properly, food particles can stay in your mouth and a sticky build-up of bacteria can form on your teeth. This build up is known as plaque. The tonsils, the uneven surface of your tongue can trap food particles and bacteria in the mouth. If that happens, they will create bad breath odour. Because of poor oral hygiene, other oral health conditions like cavities and gum disease may happen and because of them the problem of bad breath may also happen. A proper oral care routine is very important to ensure that you do not suffer from this problem.

Eating flavoured food and drink

If you eat certain foods that have flavour, they can result in bad breath. Onions, garlic, certain vegetables and spices may enter the bloodstream and may be carried to the lungs. Such foods can affect the odour of your breath each time you exhale and that can be a reason of bad breath.


Alcohol is another reason why some people have bad breath. If you drink often, you are likely to suffer from this problem. If you drink alcohol and if you drink excessively, it can decrease saliva production and when saliva production goes down it can be a very conducive environment for odour causing bacteria to flourish.


Even though many people like coffee and it is known as a must have in the morning, it can be a problem for you if you suffer from bad breath. Having coffee in the morning can leave you feeling like you have bad breath. If the coffee has intense flavour, it can result in this problem. Coffee can also reduce saliva production. The caffeine present in the coffee can result in reduction in saliva production. And as we mentioned earlier, less saliva production can result in more bacteria formation and growth, which can ultimately result in bad breath.

High sugar diets

Another very common reason bad breath is high sugar diets. If you regularly consume a diet rich in sugar and protein, you’re likely to have bad breath problem. Sugar is a good food for the bacteria present in your mouth and so when you are providing more sugar to them, it will act as a very good food for those bacteria. So that sugar will be turned into sour smells by the bacteria.

Dry mouth

If you suffer from a condition known as dry mouth, it can easily result in a bad breath condition. Saliva is necessary because it keeps your mouth clean by removing food particles that results in bad breath.
