2. Scrape your tongue
Mouth hygiene isn’t just about your teeth. Bacteria can grow on every surface of your mouth, including the inside of your cheeks, your gums, and of course, your tongue. Some people like to clean their tongue with their toothbrushes, and that helps, but it is not enough to get rid of all the potential agents of bad breath that are found on the surface of it. Your tongue has an irregular surface and bacteria can hide on the texture and grow, causing bad breath.
Also, other infections such as microscopical fungi can grow on your tongue, causing bad breath as well. Even dead cells could accumulate on your tongue, so it is important to keep it clean. You can use a tongue scraper to clean it a couple of times a day. Some toothbrushes have a tongue scraper on the back, so you can use both. Another good option is to use a spoon to scrape your tongue.
