Can Baking Soda Prevent Bad Breath?

The one efficient answer to bad breath is baking soda. Baking soda or sodium bicarbonate is a unique composition indeed. Here is how it works for bad breath –

  • It is alkaline in nature and neutralizes the high acidic levels in your mouth that are the cause for bad breath (1).
  • It kills the bacteria in the mouth that thrive in an environment rich in acidity and sucrose, by utilizing its antimicrobial properties (2).
  • Since it is not acidic, it causes no harm to the teeth, gums or bones.
