It doesn’t matter how often you brush your teeth daily; you’ll still have bad breath if you don’t clean your tongue.
When you see your tongue looks whitish or yellowish, it’s a sign for you to clean it.
A white or yellow tongue results from bacteria building up on your tongue, which can eventually reach your teeth and gums.
This makes brushing your teeth less effective in protecting them from oral health problems.
You can use the backside of your toothbrush to clean your tongue, but using a tongue scraper does a better job of removing bacteria and preventing bad breath.
