Bad Breath Smell
Have you always wondered why bad breath smells the way it does? It is indeed a fascinating thought when you consider how such obnoxious smell can emanate from your mouth! A bad breath smell is usually a byproduct of anaerobic bacteria living in your mouth. These bacteria process proteins and produce amino acids, which are then broken down into several other compounds. Among these methyl mercaptan and hydrogen sulfide, which smell like poop and rotten eggs respectively, are the main causes of smelly breath. Some other compounds, which smell like sulfur, mothballs and decaying flesh, are also behind your bad breath issues.
