I use a tongue cleaner to remove tongue coating.

There was a time when I thought I had bad breath. I think I was afraid of using a tongue cleaner because I was young back then.

Because I didn't know how to use it, using a tongue cleaner used to make me gag.

Now that I have mastered the usage, I have learned how to cleanly remove the coating from only the tongue.

There are many famous tongue cleaners, but I saw an experiment somewhere that said that particular product isn't particularly good.

Everyone needs to find a product that suits their own taste.
