Brushing and Flossing 

Bad breath, also called “halitosis,” is most commonly caused by plaque build-up on your teeth and gum surfaces. Plaque consists of bacteria, which feeds on the sugars in your mouth. If plaque is not routinely cleaned off your teeth and gums, it leads to gum disease and cavities. Therefore, the more plaque you have on your teeth and gums, the more likely you are to experience bad breath. Brush your teeth at least twice a day and floss at least once daily to remove plaque to keep your teeth and gums healthy. 

Cleaning Your Tongue 

Your tongue is a rough surface that can harbour lots of bacteria. In addition, the top surface of your tongue is filled with thousands of taste buds from the back to the tip, which creates many crevices where plaque builds up. Make sure to clean your tongue daily with either your toothbrush or a tongue cleaner.
