Your breath may be smelling like a combination of rotten eggs, feces, cabbage, sulfer and gasoline! Volatile sulfer compounds (VSCs) are released with the breakdown of food and blood. Removing food from your tongue, teeth and from the spaces in between your teeth with toothbrush and floss after meals is critical to improving your breath. Fifty percent of the population suffers from bad breath with ninety percent of the smelly breath being due to the mouth. If your gums are bleeding when you brush or floss you need to visit the dentist to get a thorough cleaning and improve your breath.
