10. A “dirty” tongue
Your tongue is one of the most common causes of bad breath. The “fur” on your tongue acts like a shag carpet where food particles, bacteria and post-nasal drip can accumulate, creating the ideal conditions for bacteria to breed. A toothbrush isn’t the best tool to use to clean your tongue because it’s designed to clean your teeth. A tongue cleaner or tongue scraper is an oral-hygiene device designed to clean the sludge that collects on the surface of your tongue. Cleaning your tongue regularly can make a huge difference in the quality of your breath.
