Tongue Cleaning
If you are suffering of bad breath you might consider using tongue cleaner to treat it because most of bad breath is coming from back of your tongue. Most of new tooth toothbrushes include now days tongue cleaner on backside of brush.
You might want to try some other ways to get clean your tongue like mouthwashes and anything to sweep bacteria away from top of your tongue. Many use toothbrush but its not ideal to it because it is too big to get at the back of your mouth and if you use it it may cause gag effect and make tongue cleaning process unpleasant.
As a tongue scraper is designed to it and I highly recommend to buy one of those for better results. As a major part of bacteria witch cause bad breath is back of your tongue it is very important to reach there nicely. How ever if you dont have afford it you might use regular spoon to scrape bacteria away from your tongue. it’s not designed for it but it’s much better option than toothbrush. How ever be careful not to scrape sensitive tissue from back of your mouth.
