Bad breath is caused by bacteria in the mouth or between the teeth. Pure Silver rinse can destroy these bacteria and gets rid of the bad breath. When food is eaten the digestion begins in the mouth with chewing and salivary fluids. Our food is broken down into tiny particles that can be used as fuel around the body. However, much of the food stays in our mouths as both visible and microscopic particles. These particles if not removed from the mouth and hard to get to places, such as between the teeth, can result in the food rotting and becoming bacteria.
