Five reasons you have bad breath

Do you have bad breath? If so, do you know what is causing it? Bad breath is not only unpleasant and too common, it is also very shameful. Here the 5 main causes of bad breath are addressed.

Poor oral hygiene

To reduce bad breath, it is essential that you maintain good oral hygiene. Poor oral hygiene can be a major contributor to bad breath and can also play an important role in other diseases.

Harmful bacteria can attack tooth enamel that causes tooth decay. Therefore, it is very important to brush and floss regularly, because microorganisms can live in the toothbrush and infect the mouth, you should make sure to clean your toothbrush regularly and change it every 3 months.

Eat foods that cause bad breath

Onions, garlic and foods with strong aromatic flavors affect the air you exhale if you have eaten them. Once you start chewing food, the saliva enzymes in the mouth begin the digestion process.

This food once absorbed into the bloodstream, is transferred to the lungs resulting in a bad smell when exhaling air. Sucking a peppermint, brushing or using mouthwash only helps to mask these bad odors.

Infection in the lungs and allergies

The proteins found in phlegm and mucus often attract bacteria that cause mouth odour. Your nostrils produce extra mucus when you have allergies, an unusual infection or a cold. This causes your breath to have an unpleasant odor as the extra mucosa is directed to the back of the throat, and when exhaling the air the odor is expelled.

Diseases of the gums

Gum disease is a bacterial infection known as periodontal disease and resides in the tissue surrounding the teeth. Because of this, bacteria accumulate in the infected gums. People with these types of problems are more likely to suffer from bad breath. If you suspect that you have a problem with the gums, it is necessary that you attend the dentist in the shortest possible time.

Untreated medical conditions

Allergic rhinitis, chronic sinusitis, diabetes and bronchitis are serious diseases that also cause bad breath. Having an unusual smell in your mouth can be a sign that you have any of these diseases.


Another cause of bad breath is smoking. Smoking affects the flow of saliva in the mouth causing dryness in the mouth, causing your breath to have a smell similar to an ashtray. Smoking not only causes bad breath, it can also lead to heart disease and also a variety of cancers, including oral cancer, so avoid smoking.
