Using a probiotic is a great way to combat bad breath. It is usually caused by an overgrowth of odor-producing bacteria in the mouth. These bacteria release foul-smelling gases, such as volatile sulphur compounds.

The good news is that there are several types of probiotics that are proven to reduce bad breath. Probiotics are known to help protect your teeth and gums. They are able to prevent plaque buildup and decrease gum inflammation.
