Pyuora 泡沫牙膏（清新薄荷味），110毫升

I bought it out of curiosity, but it turned out to be even better than I expected. Simply place the foam directly on your tongue and swish it around for 10 seconds to cleanse and kill the bacteria on your tongue that cause bad breath. There's no need to scrub your tongue, so it's gentle on your tongue. The foam cleanses your mouth and leaves you feeling refreshed, and best of all, it makes you want to brush your teeth. It's a convenient product that can be used as both a mouthwash and a toothbrush all at once. It's more expensive than regular toothpaste, but I think the benefits are worth it.

It's easy! Isn't tongue brushing for bad breath so tough? It makes you gag, takes time, and is tiring, so I saw an ad and bought it. Just put it on the bottom before brushing your teeth, let it sit for about 10 seconds, then apply toothpaste as usual and brush your teeth. Of course, the foaming power increases while you brush your teeth, so it makes your mouth feel thicker than usual, but I like the feeling of it leaving your tongue nice and smooth without any unpleasant irritation.

It removes dirt and plaque from the tongue well. I don't find it particularly unpleasant, other liquid toothpastes taste worse. I decided to buy it again after a long time, and was surprised to find that it had become so much smaller.
