Causes of Bad Breath
Smoking & Tobacco: An absolute contributor to bad breath.
What you consume: Certain foods such as garlic and onion cause bad breath. Alcohol is also a contributor to bad breath.
What you don’t consume: People who are following certain diet regimens such as the Atkins or other protein rich diets with minimal or no carbohydrates can experience bad breath.
Systemic Disease & Infections: Certain chronic medical conditions such as diabetes, sinusitis, bronchitis, respiratory tract infections, liver or kidney disease, and other conditions can cause bad breath.
The Nose: Is the second most common cause of bad breath.
The Mouth: Is the most common cause of bad breath.
Dry Mouth: Also known as Xerostomia; can cause bad breath. Due to reduced saliva flow, the ability to wash away food particles increases bacterial build up in the mouth, which is a primary contributor to bad breath.
Dental Caries and Infections: Since dental caries and infections are caused by bacteria, the presence of bacteria or gum disease can cause bad breath.
Bacteria on the tongue: This is the primary reason for chronic bad breath, especially in the absence of any of the aforementioned conditions.
