There’s nothing worse than meeting someone and realizing that your breath smells like your tuna lunch, stale coffee or worse. What you eat and poor oral hygiene are the two main causes of halitosis, or bad breath.
When you think about it, the mouth is a dirty worksite: more than 600 kinds of bacteria live in the average mouth. Many produce smelly gases as they digest the tiny food particles lodged between your teeth and on your tongue. Some of the most offensive gases produced by mouth bacteria are sulfur compounds, which are formed during the breakdown of proteins. Garlic and onion also contain many sulfur compounds.
