The bacteria that can cause bad breath or maybe halitosis can affect anyone. No one is able to avoid having bacteria as they serve an important function in the bodies of ours. Bacteria are able to assist with the digestion process by breaking down the proteins present in mucus, foods, and blood. But bacteria are able to wreck your breath when there is an extra supply of them. Halitosis is going to occur whether bacteria break down proteins much too quickly. These protein-rich foods will be converted into Volatile Sulfur Compounds (VSCs), and they are responsible for making your breath stink.
