The most common reason that people recognize as causing bad breath is the food that they eat. Obviously, what you take into your mouth affects the air that you then breathe out; garlic, onions, and other strong flavors often contribute to offensive breath odor. However, what many people don’t realize about these foods is that removing their remnants from the mouth by brushing, flossing, and other oral hygiene methods will not completely remove the odor until the food is out of the body completely. Even as it is in the bloodstream and the lungs, it can continue to make its presence known. However, there are also other causes of bad breath aside from this well-known source.
- If you don’t eat very often, you may experience bad breath.
- If particles of food remain in your mouth and collect bacteria (whether it’s between the teeth, on the tongue, or around the gums) as a result of infrequent brushing, unpleasant breath may result.
- Dry mouth (xerostomia) can also cause bad breath because of the lack of saliva.
- The use of tobacco products causes disagreeable breath.
- Medical disorders including bronchitis, diabetes, sinus infections, and others, often cause bad breath.
