I recommend a tongue cleaner.

I chose this product because I liked the antibacterial feature.

Other products smelled and felt unpleasant even after boiling them, so I purchased this cleaner that claims to be antibacterial.

It's so soft and wipes off so easily, I love it lol

Otherwise, my tongue gets a white coating and looks weird ㅠㅠㅠ You really have to try this. It's so great because it disinfects too!
