Having bad breath is embarrassing. And to make matters worse, you might not even realize you have it.
Your nose loses its sensitivity to the smell of your breath and is unable to detect the disagreeable smell. It would be extremely embarrassing for other people to have to tell you the terrible news. Halitosis is the medical term used for bad breath. Everyone occasionally has bad breath, especially after consuming foods with strong flavors like garlic, onions, or other pungent flavors. However, persistent bad breath (chronic halitosis) may be a sign of an oral health issue or a disease that is affecting another part of your body. Halitosis is a symptom of a number of medical conditions. It can significantly reduce your sense of worth and self-esteem. You may feel compelled to distance yourself from interpersonal connections and communication because you are aware that your breath is not as fresh as it ought to be. As a result, you may experience significant emotional and psychological strain. If you have bad breath, the quality of your life may suffer significantly. The first step in treating halitosis is determining what is causing it.

The cause, which could be any of the following, is what ultimately determines the course of treatment. 

• food and beverage
• oral hygiene issues
• gum illness
• smoking
• dieting
• medication
• health issues
