Also known as halitosis, can be caused by a variety of factors, including poor oral hygiene, certain foods and drinks, dry mouth, smoking, and even underlying health conditions. While most cases of bad breath are related to oral hygiene, persistent bad breath that doesn’t improve with regular brushing and flossing may indicate a more serious issue.

Common Causes of Bad Breath:

Poor Oral Hygiene:

This is the most common cause, where bacteria build up in the mouth due to inadequate brushing and flossing, leading to plaque and food debris accumulation.

Food and Drinks:

Onions, garlic, coffee, and other strong-smelling foods can contribute to bad breath, as their odors can be absorbed into the bloodstream and released through the lungs.

Dry Mouth (Xerostomia):

Reduced saliva flow can allow bacteria to thrive and cause bad breath. Dry mouth can be caused by medications, alcohol consumption, and certain medical conditions.

Smoking:

Smoking dries out the mouth and can cause a build-up of bacteria on the tongue and teeth, leading to bad breath.

Underlying Medical Conditions:

In some cases, bad breath can be a symptom of more serious health issues like respiratory infections, diabetes, liver or kidney problems, or even certain cancers.
